Acts 3:16

And his name through faith in his name hath made this man strong, whom ye see and know: yea, the faith which is by him hath given him this perfect soundness in the presence of you all.

EXPOSITORY (ENGLISH BIBLE)

Ellicott's Commentary for English Readers

(16) His name through faith in his name.—We have, in technical language, the efficient cause distinguished from the indispensable condition of its action. The Name did not work as a formula of incantation; it required, on the part both of the worker and the receiver, faith in that which the Name represented, the manifestation of the Father through the Son.

Hath made this man strong.—The verb is the same as that which had been used in Acts 3:7 of the “feet and ankle-bones.” It was Jesus who had given them that new firmness.

The faith which is by him.—The causation of the miracle is carried yet another step backward. The faith which was alike in the healer and in the man healed was itself wrought in each by the power of Christ. The man was first a willing recipient of that faith spiritually, and then was in a state that made him worthy to be a recipient also of the bodily restoration.

This perfect soundness.—Literally, this completeness. This is the only passage in the New Testament in which the word occurs. The cognate adjective is found in the “whole” of 1Thessalonians 5:23; the “complete” of James 1:4.

Acts

‘THEN SHALL THE LAME MAN LEAP AS AN HART’

THE HEALING POWER OF THE NAME

Acts 3:16.

Peter said, ‘Why look ye so earnestly on us, as though by our own power or holiness we had made this man to walk?’ eagerly disclaiming being anything else than a medium through which Another’s power operated. Jesus Christ said, ‘That ye may know that the Son of Man hath power on earth to forgive sins, I say unto thee, Arise, take up thy bed, and walk’-unmistakably claiming to be a great deal more than a medium. Why the difference? Jesus Christ did habitually in His miracles adopt the tone on which Moses once ventured when he smote the rock and said, ‘Ye rebels! must we bring the water for you?’ and he was punished for it by exclusion from the Promised Land. Why the difference? Moses was ‘in all his house as a servant, but Christ as a Son over His own house’; and what was arrogance in the servant was natural and reasonable in the Son.

The gist of this verse is a reference to Jesus Christ as a source of miraculous power, not merely because He wrought miracles when on earth, but because from heaven He gave the power of which Peter was but the channel. Now it seems to me that in these emphatic and singularly reduplicated words of the Apostle there are two or three very important lessons which I offer for your consideration.

I. The first is the power of the Name.

Now the Name of which Peter is speaking is not the collocation of syllables which are sounded ‘Jesus Christ.’ His hearers were familiar with the ancient and Eastern method of regarding names as very much more than distinguishing labels. They are, in the view of the Old Testament, attempts at a summary description of things by their prominent characteristics. They are condensed definitions. And so the Old Testament uses the expression, the ‘Name’ of God, as equivalent to ‘that which God is manifested to be.’ Hence, in later days-and there are some tendencies thither even in Scripture-in Jewish literature ‘the Name’ came to be a reverential synonym for God Himself. And there are traces that this peculiar usage with regard to the divine Name was beginning to shape itself in the Church with reference to the name of Jesus, even at that period in which my text was spoken. For instance, in the fifth chapter we read that the Apostles ‘departed from the council rejoicing that they were counted worthy to suffer shame for the Name,’ and we find at a much later date that missionaries of the Gospel are described by the Apostle John as going forth ‘for the sake of the Name.’

The name of Christ, then, is the representation or embodiment of that which Christ is declared to be for us men, and it is that Name, the totality of what He is manifested to be, in which lies all power for healing and for strengthening. The Name, that is, the whole Christ, in His nature, His offices, His work, His Incarnation, His Life, His Death, Resurrection, Session at the right hand of God-it is this Christ whose Name made that man strong, and will make us strong. Brethren, let us remember that, while fragments of the Name will have fragmentary power, as the curative virtue that resides in any substance belongs to the smallest grain of it, if detached from the mass-whilst fragments of the Name of Christ have power, thanks be to Him! so that no man can have even a very imperfect and rudimentary view of what Jesus Christ is and does, without getting strength and healing in proportion to the completeness of his conception, yet in order to realise all that He can be and do, a man must take the whole Christ as He is revealed.

The Early Church had a symbol for Jesus Christ, a fish, to which they were led because the Greek word for a fish is made up of the initials of the words which they conceived to be the Name. And what was it? ‘Jesus Christ, God’s Son, Saviour’; Jesus, humanity; Christ, the apex of Revelation, the fulfilment of prophecy, the Anointed Prophet, Priest, and King; Song of Solomon of God, the divine nature: and all these, the humanity, the Messiahship, the divinity, found their sphere of activity in the last name, which, without them, would in its fulness have been impossible-Saviour. He is not such a Saviour as He may be to each of us, unless our conception of the Name grasps these three truths: His humanity, His Messiahship, His divinity. ‘His Name has made this man strong.’

II. Notice how the power of the Name comes to operate.

Now, if you will observe the language of my text, you will note that Peter says, as it would appear, the same thing twice over: ‘His Name, through faith in His Name, hath made this man strong.’ And then, as if he were saying something else, he adds what seems to be the same thing: ‘Yea! the faith which is by Him hath given him this perfect soundness.’

Now, note that in the first of these two statements nothing appears except the ‘man,’ the ‘Name,’ and ‘faith’ I take it, though of course it may be questionable, that that clause refers to the man’s faith, and that we have in it the intentional exclusion of the human workers, and are presented with the only two parties really concerned-at the one end the Name, at the other end ‘this man made strong.’ And the link of connection between the two in this clause is faith-that is, the man’s trust. But then, if we come to the next clause, we find that although Peter has just previously disclaimed all merit in the cure, yet there is a sense in which some one’s faith, working as from without, gave to the man ‘this perfect soundness.’ And it seems very natural to me to understand that here, where human faith is represented as being, in some subordinate sense, the bestower of the healing which really the Name had bestowed, it is the faith of the human miracle-worker or medium which is referred to. Peter’s faith did give, but Peter only gave what he had received through faith. And so let all the praise be given to the water, and none to the cup.

Whether that be a fair interpretation of the words of my text, with their singular and apparently meaningless tautology or no, at all events the principle which is involved in the explanation is one that I wish to dwell upon briefly now; and that is, that in order for the Name, charged and supercharged with healing and strengthening power as it is, to come into operation, there must be a twofold trust.

The healer, the medium of healing, must have faith in the Name. Yes! of course. In all regions the first requisite, the one indispensable condition, of a successful propagandist, is enthusiastic confidence in what he promulgates. ‘That man will go far,’ said a cynical politician about one of his rivals; ‘he believes every word he says.’ And that is the condition always of getting other people to believe us. Faith is contagious; men catch from other people’s tongues the accent of conviction. If one wants to enforce any opinion upon others, the first condition is that he shall be utterly sel-oblivious; and when he is manifestly saying, as the Apostles in this context did, ‘Do not fix your eyes on us, as though we were doing anything,’ then hearts will bow before him, as the trees of the wood are bowed by the wind.

If that is true in all regions, it is eminently true in regard to religion. For what we need there most is not to be instructed, but to be impressed. Most of us have, lying dormant in the bedchamber and infirmary of our brains, convictions which only need to be awakened to revolutionise our lives. Now one of the most powerful ways of waking them is contact with any man in whom they are awake. So all successful teachers and messengers of Jesus Christ have had this characteristic in common, however unlike each other they have been. The divergences of temperament, of moods, of point of view, of method of working which prevailed even in the little group of Apostles, and broadly distinguished Paul from Peter, Peter from James, and Paul and Peter and James from John, are only types of what has been repeated ever since. Get together the great missionaries of the Cross, and you would have the most extraordinary collection of miscellaneous idiosyncrasies that the world ever saw, and they would not understand each other, as some of them wofully misunderstood each other when here together. But there was one characteristic in them all, a flaming earnestness of belief in the power of the Name. And so it did not matter much, if at all, what their divergences were. Each of them was fitted for the Master’s use.

And so, brethren, here is the reason-I do not say the only reason, but the main one, and that which most affects us-for the slow progress, and even apparent failure, of Christianity. It has fallen into the hands of a Church that does not half believe its own Gospel. By reason of formality and ceremonial and sacerdotalism and a lazy kind of expectation that, somehow or other, the benefits of Christ’s love can come to men apart from their own personal faith in Him, the Church has largely ceased to anticipate that great things can be done by its utterance of the Name. And if you have, I do not say ministers, or teachers, or official proclaimers, or Sunday-school teachers, or the like, but I say if you have a Church, that is honeycombed with doubt, and from which the strength and flood-tide of faith have in many cases ebbed away, why, it may go on uttering its formal proclamations of the Name till the Day of Judgment, and all that will come of it will be-’The man in whom the devils were, leaped upon them, and overcame them, and said’-as he had a good right to say-’Jesus I know, and Paul I know, but who are ye?’ You cannot kindle a fire with snowballs. If the town crier goes into a quiet corner of the marketplace and rings his bell apologetically, and gives out his message in a whisper, it is small wonder if nobody listens. And that is the way in which too many so-called Christian teachers and communities hold forth the Name, as if begging pardon of the world for being so narrow and old-fashioned as to believe in it still.

And no less necessary is faith on the other side. The recipient must exercise trust. This lame man, no doubt, like the other that Paul looked at in a similar case, had faith to be healed. That was the length of his tether. He believed that he was going to have his legs made strong, and they were made strong accordingly. If he had believed more, he would have got more. Let us hope that he did get more, because he believed more, at a later day. But in the meantime the Apostles’ faith was not enough to cure him; and it is not enough for you that Jesus Christ should be standing with all His power at your elbow, and that, earnestly and enthusiastically, some of Christ’s messengers may press upon you the acceptance of Him as a Saviour. He is of no good in the world to you, and never will be, unless you have the personal faith that knits you to Him.

It cannot be otherwise. Depend upon it, if Jesus Christ could save every one without terms and conditions at all, He would be only too glad to do it. But it cannot be done. The nature of His work, and the sort of blessings that He brings by His work, are such as that it is an impossibility that any man should receive them unless he has that trust which, beginning with the acceptance by the understanding of Christ as Saviour, passes on to the assent of the will, and the outgoing of the heart, and the yielding of the whole nature to Him. How can a truth do any good to any one who does not believe in it? How is it possible that, if you do not take a medicine, it will work? How can you expect to see, unless you open your eyes? How do you propose to have your blood purified, if you do not fill your lungs with air? Is it of any use to have gas-fittings in your house, if they are not connected with the main? Will a water tap run in your sculleries, if there is no pipe that joins it with the source of supply? My dear friend, these rough illustrations are only approximations to the absolute impossibility that Christ can help, heal, or save any man without the man’s personal faith. ‘Whosoever believeth’ is no arbitrary limitation, but is inseparable from the very nature of the salvation given.

III. And now, lastly, note the effects of the power of the Name.

The Apostle puts in two separate clauses what, in the case in hand, was really one thing-’hath made this man strong,’ and ‘hath given him perfect soundness.’ Ah! we can part the two, cannot we? There is the disease, the disease of an alienated heart, of a perverted will, of a swollen self, all of which we need to have cured and checked before we can do right. And there is weakness, the impotence to do what is good, ‘how to perform I find not,’ and we need to be strengthened as well as cured. There is only one thing that will do these two, and that is that Christ’s power, ay, and Christ’s own life, should pass, as it will pass if we trust Him, into our foulness and precipitate all the impurity-into our weakness and infuse strength. ‘A reed shaken with the wind,’ and without substance or solidity to resist, may be placed in what is called a petrifying well, and, by the infiltration of stony substance into its structure, may be turned into a rigid mass, like a little bar of iron. So, if Christ comes into my poor, weak, tremulous nature, there will be an infiltration into the very substance of my being of a present power which will make me strong.

My brother, you and I need, first and foremost, the healing, and then the strength-giving power, which we never find in its completeness anywhere but in Christ, and which we shall always find in Him.

And now notice, Jesus Christ does not make half cures-’this perfect soundness.’ If any man, in contact with Him, is but half delivered from his infirmities and purged from his sins, it is not because Christ’s power is inadequate, but because his own faith is defective.

Christ’s cures should be visible to all around. A man’s own testimony is not the most satisfactory. Peter appeals to the bystanders. ‘You have seen him lying here for years, a motionless lump of mendicancy, at the Temple gate. Now you see him walking and leaping and praising God. Is it a cure, or is it not?’ You professing Christians, would you like to stand that test, to empanel a jury of people that have no sympathy with your religion, in order that they might decide whether you were healed and strengthened or not? It is a good thing for us when the world bears witness that Jesus Christ’s power has come into us, and made us what we are.

And so, dear friends, I lay all these thoughts on your hearts. Christ’s gift is amply sufficient to deliver us from all evils of weakness, sickness, incapacity: to endue us with all gifts of spiritual and immortal strength. But, while the limit of what Christ gives is His boundless wealth, the limit of what you possess is your faith. The rainfall comes down in the same copiousness on rock and furrow, but it runs off the one, having stimulated no growth and left no blessing, and it sinks into the other and quickens every dormant germ into life which will one day blossom into beauty. We are all of us either rock or soil, and which we are depends on the reality, the firmness, and the force of our faith in Christ. He Himself has laid down the principle on which He bestows His gifts when He says, ‘According to thy faith be it unto thee!’

Matthew Henry's Concise Commentary

3:12-18 Observe the difference in the manner of working the miracles. Our Lord always spoke as having Almighty power, never hesitated to receive the greatest honour that was given to him on account of his Divine miracles. But the apostles referred all to their Lord, and refused to receive any honour, except as his undeserving instruments. This shows that Jesus was one with the Father, and co-equal with Him; while the apostles knew that they were weak, sinful men, and dependent for every thing on Jesus, whose power effected the cure. Useful men must be very humble. Not unto us, O Lord, not unto us, but to thy name, give glory. Every crown must be cast at the feet of Christ. The apostle showed the Jews the greatness of their crime, but would not anger or drive them to despair. Assuredly, those who reject, refuse, or deny Christ, do it through ignorance; but this can in no case be an excuse.

Barnes' Notes on the Bible

And his name - The "name" of Jesus is here put for Jesus himself, and it is the same as saying "and he," etc. In this way the word name is often used by the Hebrews, especially when speaking of God, Acts 1:15; Acts 4:12; Ephesians 1:21; Revelation 3:4. It does not mean that there was any efficacy in the mere name of Jesus that would heal the man, but that it was done by his authority and power.

Through faith in his name - By means of faith in him; that is, by the faith which Peter and John had in Jesus. It does not refer to any faith that the man had himself, for there is no evidence that he believed in him. But it was by means of the faith which the apostles exercised in him that the miracle was performed, and was thus a fulfillment of the declaration in Matthew 17:20, "If ye have faith ...ye shall to this mountain, remove hence," etc. This truth Peter repeats two or three times in the verse to impress it more distinctly on the minds of his hearers.

Whom ye see and know - There could therefore, be no mistake. He was well known to them. There was no doubt about the truth of the miracle Acts 4:16, and the only inquiry was in what way it had been done. This Peter affirms to have been accomplished only by the power of the Lord Jesus.

Perfect soundness - ὁλοκληρίαν holoklērian. This word is not used elsewhere in the New Testament. It denotes "integrity of parts, freedom from any defect"; and it here means that the cure was perfect and entire, or that he was completely restored to the use of his limbs.

In the presence of you all - You are all witnesses of it, and can judge for yourselves. This shows how confident the apostles were that a real miracle had been performed. They were willing that it should be examined; and this is conclusive proof that there was no attempt at imposture. A deceiver, or one who pretended to work miracles, would have been cautious of exposing the subject to the danger of detection.

Jamieson-Fausset-Brown Bible Commentary

16. his name, through faith in his name, hath made this man strong, &c.—With what skill does the apostle use the miracle both to glorify his ascended Lord and bring the guilt of His blood more resistlessly home to his audience!

Matthew Poole's Commentary

His name; his power; for by it he is known, as men or things are by their several names; or the name of Christ is put for Christ himself, as the name of God is put for God commonly.

Through faith in his name; calling by faith on the name of Christ, being thoroughly persuaded that he could and would heal this cripple.

The faith which is by him; not only faith, as on Christ as its object, but by and from Christ as its author; faith being twice made mention of in this cure, there being required faith in Peter to heal, and in the lame man to be healed.

Gill's Exposition of the Entire Bible

And his name, through faith in his name,.... That is, the name of Christ, or the power of Christ, through the faith of the apostles in him, while they made use of his name, and said, "in the name of Jesus Christ of Nazareth", &c. Acts 3:6 or Christ, through the faith of the lame man in him; and when his name was used in this manner by the apostles; not that either their faith, or his, had any causal influence on the cure, but was the way and means in which they, glorifying Christ, he was pleased to effect this cure:

hath made this man strong; who was before exceeding weak; strengthened the parts that were infirm, his feet and ankles, and consolidated them, so that he could use them, and walk with them:

whom ye see and know; they knew him before, when he was lame, and now knew him to be the same man, and whom they saw now perfectly well; so that they could be appealed to that there was no fraud or imposture in the case:

yea, the faith which is by him; by Christ, of which he is the object, and the author, and finisher: this is repeated out of affection to Christ, and a passionate concern for the glory of his name; or because that faith, in one clause, may regard the faith of the apostles, and in the other, the faith of the man that was cured:

hath given him this perfect soundness in the presence of you all: he had perfect soundness both in body and mind; though the former may chiefly be designed, it being that which was only visible to these persons; and which was done, not in a corner, but publicly, before them all, at the gate of the temple, where the multitude passed to and fro.

Geneva Study Bible

And his name through faith in his name hath made this man strong, whom ye see and know: {d} yea, the faith which is by him hath given him this perfect soundness in the presence of you all.

(d) Because he believed on him who was raised from the dead, whose name he heard about from us.

EXEGETICAL (ORIGINAL LANGUAGES)

Meyer's NT Commentary

Acts 3:16. Ἐπὶ τῇ πίστει τοῦ ὀνόμ. αὐτοῦ] on account of faith in His name (which we acknowledge as that of the Messiah), i.e. because we believe in His Messiahship. On ἐπί, of the cause on which the fact rests, on the ground, of, see Bernhardy, p. 250; as to the genitive of the object with πίστις, see on Romans 3:22. Others—particularly Rosenmüller, Heinrichs, and Olshausen—understand ἐπί of the aim (Lobeck, ad Phryn. p. 475): in order that faith in Jesus may be excited in you (and at the same time in the healed man himself, according to Olshausen). But the very connection of thought is in favour of the first explanation. For καὶ ἐπὶ τῇ πίστει κ.τ.λ. attaches itself closely to the preceding οὗ ἡμεῖς μάρτυρές ἐσμεν; so that Peter, immediately after mentioning the testimony, brings forward the extraordinary efficacy of the faith on which this apostolic testimony is based. Still more decisive is the parallelism of the second clause of the verse, in which the thought of the first clause is repeated emphatically, and with yet more precise definition.

τὸ ὄνομα αὐτοῦ] so far, namely, as the cure was effected by means of His name pronounced, Acts 3:6. Observe the weighty repetition and position at the end.

ἡ πίστις ἡ διʼ αὐτοῦ] the faith wrought (in us) through Him. Through Christ was the faith (namely, in Him as the Messiah) wrought in Peter and John (and in the apostles generally), partly by means of His whole manifestation and ministry during His life (Matthew 16:16; John 1:14), partly by means of the resurrection and effusion of the Spirit. The view which takes πίστις of trust in God brought about through Christ (comp. 1 Peter 1:21; Weiss, Petr. Lehrbegr. p. 324; bibl. Theol. p. 139, after de Wette), is not in keeping with the first half of the verse, which has already specifically determined the object of πίστις.

ταύτην] δεικτικῶς. For the bodily soundness of the man, who was present (Acts 3:11), was apparent to their eyes. On ὁλοκληρ., comp. Plut. Mor. p.1063 F; Plat. Tim. p. 44 C: ὁλόκληρος ὑγιής τε παντελῶς.

ἀπέναντι πάντ. ὑμ.] corresponds to ὃν θεωρεῖτε in the first clause of the verse. The faith, etc., gave to him this restoration in the presence of you all; so that no other way of its coming to pass was at all to be thought of.

Expositor's Greek Testament

Acts 3:16. ἐπὶ: so T.R., and so Weiss and Wendt: “on the ground of faith in His name,” R.V. margin; cf. Luke 5:5 (not expressing the aim as if it meant with a view to faith in His name). But the name is no mere formula of incantation, see Acts 19:13, nor is it used as, in Jewish tradition, the name of God, inscribed on the rod of Moses, was said to have given him power to work his miracles in Egypt and the wilderness, see above on Acts 3:5. On the use of ὄνομα in formulæ of incantation, see Deissmann, Bibelstudien, pp. 25–54.—ἡ πίστις ἡ διʼ αὐτοῦ: “the faith which is through Him,” not by it, i.e., the name—not only the healing power is through Christ, but also the faith of the Apostles as of the man who was healed, cf., especially, 1 Peter 1:21. τοὺς διʼ αὐτοῦ πιστοὺς εἰς Θεόν, i.e., his converts who through Christ are believers in God: He is the object and the author of our faith, Cf. also Nestle, Expository Times, Feb., 1899, p. 238, and the connection of this phrase with Codex [143], Acts 18:8, and Acts 20:21 (see Blass, l. c.).—ὁλοκληρίαν: only here in N.T., integram sanitatem, Vulgate, but the adjective ὁλόκληρος in an ethical sense, 1 Thessalonians 5:23, Jam 1:4. The noun is only used once in the LXX, and there in a physical sense, Isaiah 1:6. The adjective is used by Josephus of a sacrifice complete in all its parts (integer), Ant., iii., 12, 2, cf. its use in Philo., but in LXX, Zach. Acts 11:16, its use in a physical sense is a very doubtful rendering of the Hebrew, see further Trench, N. T. Synonyms, i., 85, and Mayor’s St. James, p. 34. Cf. Plato, Tim., 44.—ὁλόκληρος ὑγιής τε παντελῶς. In Plutarch the noun is joined with ὑγίεια, and also with τοῦ σώματος (Grimm), but whilst the noun does not seem to be used by the strictly medical writers, ὁλόκληρος is frequently used of complete soundness of body (Hobart, Zahn).

Cambridge Bible for Schools and Colleges

16. And his name, &c.] There is more force in retaining the order of the Greek, And through faith in his name, his name hath made strong this man whom ye see and know. This use of name = power, and even as an absolute equivalent for God, is very Jewish; cp. Acts 4:12. The usage grew out of such passages as Psalm 106:8, “He saved them for His name’s sake.” In the literature of the Jews great power was attributed to the name of God even when only inscribed, e.g. as it was said in tradition to have been on the rod of Moses. By this power he is reported to have wrought the miracles in Egypt and in the wilderness. But St Peter’s language here explains that it is no such power of which he is now speaking, for the name of Jesus does not work the miracle per se but only because of the faith of the believer.

the faith which is by him] St Peter uses the like expression (1 Peter 1:21), “You who by Him do believe in God.” Christ is “the author and finisher of our faith.”

Bengel's Gnomen

Acts 3:16. Ἐπὶ τῇ πίστει, [on account of, or] upon the faith) The faith (i.e. faithfulness) of the name of Jesus is an expression drawn from the fact, that this name is a name πιστὸν, faithful, and sure (to be firmly relied on): and to this faith (or faithfulness) corresponds, presently after, the faith which is through (by) Him, viz. the faith which was in Peter, and began to be in the lame man. The correlatives are, the name of Christ, and the faith of the saints.—θεωρεῖτε καὶ οἴδατε) ye see at the present time, ye know as to the past.—τὸ ὄνομα αὐτοῦ, His name) The nominative, instead of the pronoun that, which would have reference to the preceding ὀνόματος, of His name. A similar construction occurs, 2 Chronicles 28:9, “In the wrath of the Lord God of your fathers upon Judah, (the Lord) hath given them into your hand;” 1 Samuel 24:5, “The heart of David smote him (viz. David);” Deuteronomy 9:4, “On account of the wickedness of those nations, God doth destroy them.” By an elegant retrogression [see Append, on Regressus], Peter concludes from the effect to the cause, and with great force mentions (names) name so often.—ἡ διʼ αὐτοῦ, which is by (through) Him) Peter sets down not only the act, but even faith itself, to the account of Christ and His name. Through Christ, our faith is of GOD, and tends to GOD. 1 Peter 1:21, “Who by Him do believe in God. etc., that your faith and hope might be in God.”

Pulpit Commentary

Verse 16. - By faith in his Name hath this for his Name through faith in his Name, A.V.: the order of the words is changed from that of the A.V., to bring it into accordance with the order of the Greek, but with a great loss of force in English; behold for see, A.V.; through for by, A.V. Yea, the faith; rather, and the faith. The two propositions are not the same. The first affirms that it is the Name of Jesus which has given him strength, objectively; the second that the faith (subjective) which is through or by him hath given him perfect soundness. There is some obscurity in the exact meaning of ἡ πίστις ἡ δι αὐτοῦ. Some (see Alford, 1:1) compare 1 Peter 1:21, and make God the object of the faith of his witnesses, Peter and John. Others (Meyer) understand that the faith in the Name of Christ was wrought in Peter and John by or through Christ's ministry and resurrection. But it is much more consonant with other passages (Acts 14:9; Acts 16:31, etc.; Matthew 15:28, etc.) to understand the faith to be that of the man who was healed; and then the phrase, "which is through him," will denote naturally that it was through Jesus Christ that the man's faith brought him into contact, so to speak, with God who healed him. In the same spirit we read that the lame man "praised God" (vers. 8, 9) for the cure effected through the Name of Jesus Christ; and Peter says (ver. 15), "Whom God raised from the dead." The interpretation of the phrase ἡ δι αὐτοῦ depends upon whether we supply an active or a passive word. The faith which acts, or works, or moves through him is one way of understanding it; the faith which is wrought or produced through him is the other. The first is preferable. This perfect soundness; pointing to what they saw with their own eyes while the man was leaping and dancing before them (ὁλοκληρία, perfect soundness, used only here in the New Testament; it is a medical term). Acts 3:16

Vincent's Word Studies

Through faith (ἐπὶ τῇ πίστει)

Note the article: the faith which we had; not the cripple's faith, which was not demanded as a condition of his cure. Through faith (ἐπί) is rather on account of, or on the basis of. Rev., by. Compare Acts 2:38; and see on Matthew 28:19.

Made strong (ἐστερέωσε)

See on Acts 3:7.

Ye see (θεωρεῖτε)

See on Luke 10:18.

Perfect soundness (ὁλοκληρίαν)

Only here in New Testament. From ὅλος, entire, and κλῆρος, a lot. Denoting, therefore, the condition of one who has his entire allotment.
