vs. 108 — Accept, I pray, the freewill offerings of my mouth, O Lord, And teach me Your judgments.

John Calvin:

This verse may be read in one connected sentence, as well as divided into two members. According to the former view, the sense will be, Receive, O Lord, my sacrifices, to this end, that thou mayest teach me thy commandments. If we prefer dividing the verse into two clauses, then it will consist of two separate prayers; first, a prayer that God would accept the prophet’s sacrifices; and, secondly, a prayer that he would instruct him in the doctrine of the law. I am rather inclined to follow the first opinion. The prophet affirms, as we have seen elsewhere, that nothing was more precious to him than to understand the doctrine of the law. Lord, as if he had said, do thou, according to thy good pleasure, accept the sacrifices which I offer thee; and as my chief desire is, to be instructed aright in thy law, grant that I may be a partaker of this blessing, which I am so anxious to obtain.

It was the design of God, by that ceremony, to testify to the fathers that no prayers were acceptable to him, but those which were joined with sacrifice, that they might always turn their minds to the Mediator. In the first place, he acknowledges that he was unworthy of obtaining any thing by his prayers, and that, if God heard him, it proceeded from his free and unmerited grace. (Calvin, J., & Anderson, J. (2010). Commentary on the Book of Psalms (Vol. 4, pp. 482–483). Bellingham, WA: Logos Bible Software.)

Prayer:

O’ God, Father of Righteousness and Truth, I know with certainty that my prayers are wholly accepted and delightful to You. I know this because Jesus Christ is my Mediator and High Priest. He has made all that pertains to me holy, blameless, and beyond reproach. He has made my prayers sweet to Your ears. When I think of such, I am shut up and truly beside myself. With such confidence in my Christ, I request knowledge and understanding in Your word, Your ways, and judgments. Humble this child and teach me. Grant me a meek–teachable, spirit. I ask this also for all the saints. Grant us to know You and Your ways.
