Psalms 40:8

I delight to do thy will, O my God,....

It was to Christ his me at and drink to go on with the work appointed to him ( John iv. 34 ); and the reason here given is, Thy law is within my heart; it is written there, it rules there. It is meant of the law concerning the work and office of the Mediator, what he was to do and suffer; this law was dear to him and had an influence upon him in his whole undertaking.

I delight to do thy will, O my God. Our blessed Lord alone could completely do the will of God. The law is too broad for such poor creatures as we are to hope to fulfil it to the uttermost: but Jesus not only did the Father's will, but found a delight therein; from old eternity he had desired the work set before him; in his human life he was straitened till he reached the baptism of agony in which he magnified the law, and even in Gethsemane itself he chose the Father's will, and set aside his own.

50:5 (though by a different word in Hebrew) denotes obedience by the common figure of hearing for obeying, it is evident that the clause is designed to express a devotion to God's will as avowed more fully in Ps 40:8, and already explained.

I delight to do thy will, O my God. Our blessed Lord alone could completely do the will of God. The law is too broad for such poor creatures as we are to hope to fulfil it to the uttermost: but Jesus not only did the Father's will, but found a delight therein; from old eternity he had desired the work set before him; in his human life he was straitened till he reached the baptism of agony in which he magnified the law, and even in Gethsemane itself he chose the Father's will, and set aside his own. Herein is the essence of obedience, namely, in the soul's cheerful devotion to God: and our Lord's obedience, which is our righteousness, is in no measure lacking in this eminent quality. Notwithstanding his measureless griefs, our Lord found delight in his work, and for "the joy that was set before him he endured the cross, despising the shame." Yea, thy law is within my heart. No outward, formal devotion was rendered by Christ; his heart was in his work, holiness was his element, the Father's will his meat and drink. We must each of us be like our Lord in this, or we shall lack the evidence of being his disciples. Where there is no heart work, no pleasure, no delight in God's law, there can be no acceptance. Let the devout reader adore the Saviour for the spontaneous and hearty manner in which he undertook the great work of our salvation.

WE have, in the use made of the passage by the inspired Apostle, sufficient authority for applying the quotation from the 40th Psalm to our Divine Lord and Savior Jesus Christ. With such a commentary, we are sure of our way and our whereabouts.

WE have, in the use made of the passage by the inspired Apostle, sufficient authority for applying the quotation from the 40th Psalm to our Divine Lord and Savior Jesus Christ. With such a commentary, we are sure of our way and our whereabouts. We might have been perplexed as to its meaning had it not have been for this, although I think, even without the guidance of the New Testament passage, those who are familiar with Holy Writ would have felt that the words could not be fulfilled in David, but must belong to a greater than he, even to the Divine Messiah, who, in the fullness of time, would come into the world. We rejoice that the Lord Jesus, Himself, here speaks of Himself. Who but He can declare His own generation? Here He is both the subject of the Words and the Speaker. The Word is from Himself and of Himself and so we have double reason for devout attention. He tells us what He said long ago. He declares, "Then I said, Lo, I come." Because He has come to us, we gladly come to Him, and now we reverently wait upon Him to hear what our Lord shall speak, for, doubtless, He will speak peace to us, and will cause us to learn, through His Spirit, the meaning of His Words. O Savior, say to each of our hearts, "Lo, I come"! I. Without further preface, I call upon you to notice, first, THE SWEEPING AWAY OF THE SHADOW. "Sacrifice and offering You did not desire. . .burnt offering and sin offering have You not required." When the Son of God is born into the world, there is an end of all types by which He was formerly prefigured. The symbols end when the Truth, itself, is made fully manifest. The sacrifices of the Law had their times and place, their teaching and their influence.

To do thy will - God willed not the sacrifices under the law, but he willed that a human victim of infinite merit should be offered for the redemption of mankind. That there might be such a victim, a body was prepared for the eternal Logos, and in that body he came to do the will of God; that is, to suffer and die for the sins of the world. 1. Hence we see that the sovereign Will of God is that Jesus should be incarnated; that he should suffer and die; or, in the apostle’s words, taste death for every man; that all should believe on him, and be saved from their sins; for this is the Will of God, our sanctification. 2. And as the apostle grounds this on the words of the Psalm, we see that it is the Will of God that that system shall end; for as the essence of it is contained in its sacrifices, and God says he will not have these, and has appointed the Messiah to do his will, i.e., to die for men, hence it necessarily follows, from the psalmist himself, that the introduction of the Messiah into the world is the abolition of the law; and that his sacrifice is that which shall last for ever.

I delight to do thy will, O my God - To wit, in obeying the law; in submitting to all the trials appointed to me; in making an atonement for the sins of men. See the notes at Heb 10:7. Compare Php 2:8; Mat 26:39. Yea, thy law is within my heart - Margin, “In the midst of my bowels.” So the Hebrew. The idea is, that the law of God was within him. His obedience was not external, but proceeded from the heart. How true this was of the Redeemer it is not necessary here to say.
