Knowledge and Mercy in the New Covenant
Hebrews 8:11, 12
And they shall not teach every man his neighbor, and every man his brother, saying, Know the Lord: for all shall know me…


And they shall not teach every man his neighbor, etc.

I. MAN'S KNOWLEDGE, OF GOD UNDER THE NEW COVENANT. "And they shall not teach every man his fellow-citizen, and every man his brother, saying, Know the Lord," etc. We have here:

1. The highest subject of knowledge. "The Lord: all shall know me?" This is life eternal, that they should know thee the only true God," etc. This knowledge is:

(1) Sublimest in its character. There is no knowledge so exalted as this. Knowledge of astronomy is a high attainment; but it is not to be compared with knowledge of him who made the stars and all worlds, and who sustains them and presides over them.

(2) Widest in its extent. He is infinite, and can never be fully known by man: "The knowledge of God and of Christ," says Dr. Harris, "is the sum of all science; this is the only knowledge that can incorporate and mingle with our being; and all other knowledge is real only so far as it is symbolical of this."

(3) Mightiest in its moral influence. It transforms the character of those who possess it (cf. 2 Corinthians 3:18).

2. The purest source of knowledge. The obligation of men under the old covenant to impart to each other the knowledge of God is implied in the text. This obligation is not abolished under the new covenant; but there is less need for such private instruction because of the frequent public services of qualified ministers of the gospel. Moreover, the text undoubtedly refers to the communication of knowledge by the Holy Spirit. "The agency of the Holy Ghost is assumed under this covenant as 'the Spirit of truth,' the supreme and most vital Teacher of this true knowledge of God. For the covenant, taken in the large sense of a system of agencies, is definitely and certainly the gospel age as distinguished from the Mosaic; and of this gospel age or dispensation, the gift of the Holy Ghost, to teach, impress, and enforce the true knowledge of God, is the center and the soul, even as Jesus is the center and soul of the Christian economy considered as 'the Propitiation for our sins,' and our great High Priest before the throne of God. The results as given here come of his teaching and of no other" (H. Cowles, D.D.). This knowledge does not spring from mere human conjecture, or imagination, or investigation, or ratiocination; but from spiritual revelation. "All thy children shall be taught of the Lord." "Ye have an anointing from the Holy One, and ye know all things" (1 John 2:20, 27).

3. The clear apprehension of knowledge. Proceeding from so crystalline a source, the stream will be clear. If our mind and heart be free from prejudice, then the instruction concerning God which we receive from the Word and the Spirit will be clear and correct; what we know of him we shall know truly.

4. The wide diffusion of knowledge. "All shall know me, from the least to the greatest of them." Primarily the "all" refers to the "people" (ver. 10) of God: all of them shall know him. But eventually there shall be a universal diffusion of the knowledge of God. This the sacred Scriptures distinctly affirm (Matthew 24:14; Matthew 28:19; Luke 24:47; Revelation 14:6).

II. GOD'S MERCY TO MAN UNDER THE NEW COVENANT. "For I will be merciful to their unrighteousness, and their sins," etc. Under the new covenant God manifests his rich grace in the way in which he forgives sin. We have here:

1. The source of forgiveness. "I will be merciful." Forgiveness does not spring from man's repentance, but from God's mercy. Repentance is a condition of forgiveness, but the grace of God is its source. Apart from his grace repentance is impossible unto us. "By grace are ye saved," etc. (cf. Ephesians 2:7-10).

2. The fullness of forgiveness. He pardons "their iniquities and their sins." He cleanses "from all unrighteousness." "The blood of Jesus Christ his Son cleanseth us from all sin." None are too numerous, none too aggravated, etc. (cf. Isaiah 1:18; Isaiah 4:7).

3. The irrevocableness of forgiveness. "Their sins will I remember no more." Strictly speaking, the Infinite Mind cannot forget anything. But God forgives so completely that the sins are as it were buried in deep oblivion. His forgiveness is irrevocable. This inspiring truth is repeatedly and impressively expressed in the Bible (Psalm 103:12; Isaiah 38:17; Isaiah 43:25; Isaiah 44:22; Micah 7:19). This rich, abounding mercy is the reason of man's fuller, clear knowledge of God. There was mercy in the old covenant, but in that it was not pre-eminent as in the new one. The chief feature of that was Law; the chief feature of this is grace. Forgiveness leads to gratitude and love to the Forgiver; and love leads to the clearer, wider knowledge of him. If you would know God truly, intimately, deeply, you must love him. - W.J.
