Preserve my soul. In the Old Testament the term "soul" is often used as we use the term "life." But there always seems within the term more or less perfect apprehension of the truth that the soul is the man. The commonly received division of man's being is into "body "and "soul;" but a more scientific analysis divides into body - which includes animal soul, or life - and spirit. The "tripartite division" is body, soul, spirit. As a moral redemption, the work of Christ has brought prominently before us that man is a spiritual being. As Dr. George Macdonald expresses it, "We are accustomed to say that we are bodies, and have souls; whereas we should say - We are souls, and have bodies."

I. MAN'S SOUL IS THE SPHERE OF GOD'S MORAL TRAINING. We may see God in history; but his supreme interest is in characters, not in events. We may see God in providence; but we fail to see him aright, unless we trace the influence of incidents on our principles and on our spirit. Everything has a moral side and a moral mission. God is ever moulding disposition and character, which are the shapings of the soul. This is true of every man. Humanity to God is a collection of spirits, or spiritual beings, set for their moral training in varied bodily forms and relations.

II. MAN'S SOUL IS THE SPHERE OF GOD'S REDEMPTIONS. The mistake made about Christ the Saviour in the days of his flesh was quite a representative mistake. Men thought he came to deliver a nation from foreign dominion; whereas he came to save souls from sin. The body redemptions follow on as the natural consequences of the spiritual redemptions. God's great work is saving souls from death. Therefore it is that before we can hope that Christ and his work will ever be appreciated, we are compelled to awaken soul anxiety; or, in other words, seek to produce conviction of sin. When our Lord's saving work is fully studied as a moral redemption, a quickening of souls with a Divine life rather than an adjustment of broken external relations, the full mystery of it will be revealed and realized.

III. MAN'S SOUL IS THE SPHERE OF THE DIVINE SANCTIFYINGS. The present work of the living Christ, realized by us as the inworking of the Holy Ghost, is not the change of the things with which we have to do, but a change of the relations in which we stand to the things; a change wrought in us - wrought in the souls that we are. This change, in effect, changes the character of the things with which we have to do. - R.T.

In such a prayer-psalm as this, there is no studying of language: it is the pouring out of the heart as the heart boils over, the utterance of the desires as they bubble up from the soul's deeps, with an entire carelessness as to the fashion of the expression. This ought to be a hint to you when you pray. Do not study how to arrange your words when you come before the Lord. When your heart is like a boiling geyser, let it steam aloft in pillars of prayer. The overflowing of the soul is the best praying in the world.

I. David in his prayer sought, beyond all things, to have PERSONAL INTERCOURSE WITH GOD. To my mind that is just the distinction between prayer before conversion and prayer after it. Note well that David, while he thus sought to have dealings with God, to come to close grips with the Lord in the act of prayer, was not presumptuously bold. He perceives the condescension of such fellowship on God's part. This may be seen in the first line: "Bow down Thine ear, O Lord, hear me." As if he said, "Thou art so high that, unless Thou shalt stoop very low, Thou canst not commune with me. But, Lord, do thus stoop. Bow down Thine ear. From Thy lofty throne, higher than an angel's wing can reach, stoop Thou down and listen to me — poor, feeble me." As you further read in this psalm, you will notice that David, in order to obtain this high privilege, pleads his need of it. He cries, "I am poor and needy"; as much as to say, "Lord, do come to me, do let me have personal intercourse witch Thee, for nothing else will serve my turn. I am so poor that Thou alone canst enrich me; I am so feeble that Thou alone canst sustain me. Thou hast made me: Lord, forsake not the work of Thine own hands; I, Thy child, am full of wants, which Thou only canst supply. Oh, deal with me in great compassion!" He next pleads his personal consecration: "Preserve my soul, for I am holy" — consecrated and dedicated to the Divine service. Moreover, David, anxious to use every argument, pleads his trust: "Save Thy servant that trusteth in Thee." This is s conquering plea: "Lord, my sole reliance is on Thee; come to me, then, and justify the confidence which Thou Thyself hast inspired." Then, notice that David pleads for God's presence because He is God's servant. "Save Thy servant." He urges yet another reason why just now he should see God, namely, that he is always in prayer: "I cry unto Thee daily." Blessed are we when prayer surrounds us like an atmosphere. Then we are living in the presence of God; we are continually conversing with Him. May we climb to the top of the mount of communion, and may we never come down from it! David also tells the Lord that, when he could not attain to the nearness he desired, yet he struggled after it, and strained after it. Now, when a man's daily cries and inward strivings are after God, he may certainly expect that God in prayer will have intercourse with him. There are occasions with all His people when the Lord brings them very near, and speaks with them, and they with Him, when His presence is to them as real as the all-pervading air, and they are as much rejoiced in it as in the presence of father, or wife, or child, or friend. Still David, conscious of the great privilege which he sought, was not content without pleading the master argument of all: he pleads the great goodness of the Lord. "For Thou, Lord, art good." As much as to say, "If Thou wert not good Thou wouldst never listen to me. I am, as it were, a noxious insect which a man might far sooner crush than speak with; and yet Thou art so good, my God, that instead of setting Thy foot on me, Thou dost lift me up and talk with me."

II. DAVID DESIRED PERSONAL ANSWERS FROM GOD. We hear our fellow-Christians say, when we tell them of instances in which God has heard our prayers, "How very extraordinary!" And we look at them, and say, "Extraordinary?" Has it become an extraordinary thing for God to be true to His own promise? I like better the remark of the good old lady, who, when her prayer was answered, was asked, "Does it not surprise you?" She said, "No, it does not surprise me; it is just like Him." A promise is like a cheque. If I have a cheque, what do I do with it? Suppose I carried it about in my pocket, and said, "I do not see the use of this bit of paper, I cannot buy anything with it," a person would say, "Have you been to the bank with it?" "No, I did not think of that." "But it is payable to your order. Have you written your name on the back of it?" "No, I have not done that." "And yet you are blaming the person who gave you the cheque! The whole blame lies with yourself. Put your name at the back of the cheque, go with it to the bank, and you will get what is promised to you." A prayer should be the presentation of God's promise endorsed by your personal faith. We expect our God to answer our prayer all the more surely when we are in trouble. David so expected: "In the day of my trouble I will call upon Thee: for Thou wilt answer me." Trouble is sent to make us pray. When we pray, the prayer becomes the solace of our trouble; and when the prayer is heard, it becomes the salvation out of our trouble. Many of you would be out of trouble quickly if you prayed. "Sir, I have been doing my best." And what is your best? A better thing than your best is to wait upon the Lord. Now, if we expect God to answer us, we do so on very good grounds. There are certain natural reasons. I was turning over in my mind the question, "Why do I pray? Why have I any reason to believe that God hears me?" And I thought to myself, "Well, on natural grounds I have a right to believe that God will hear prayer, or otherwise why is prayer commanded?" The Scripture is full of prayer. It is an institution of the old covenant, as well as of the new, and yet it is a piece of folly if God does not hear it. Observe, again, that prayer has been universal among all the saints. There have been saints of different moulds and temperaments, but they have all prayed. Some of them have been, like Heman and Asaph, masters of song, and they have prayed; others could not sing, but they have all prayed. But, if you turn to scriptural reasons, why was there a mercy-seat if there is nothing in prayer? Why does the throne of grace still remain as a permanent institution, of which Paul says, "Let us come boldly to the throne of grace," unless there is a reality in it? Tell me, why is Christ the way to the mercy-seat? Why is He Himself the great Intercessor and Mediator, if there is nothing in prayer?. The Holy Ghost helpeth our infirmities in prayer; surely there must be something effectual where He lends His aid. What! is He, after all, helping us to do a thing which produces no result? For, once more, we know that God hears prayer, because we have met with multitudes of His people who can tell of answers to prayer.
