Read Full Chapter →After speaking of sacrifices and offerings, the psalm turns to a personal response. The question is no longer only what is brought before God, but whether the worshipper himself comes ready to hear and obey. This line matters because it joins God's revealed purpose with a willing heart. It also prepares for the fuller confession of delight in God's will in the next verse.
Psalm 40:7 records a willing answer to God: the speaker comes before Him, aware that his life and calling stand within the witness God has given in the book.
The Context of Psalms 40:7
Psalm 40 begins as David's thanksgiving for rescue. The LORD heard his cry, lifted him from danger, established his steps, and put praise in his mouth. David then marvels at God's works and thoughts toward His people. Verses 6 through 8 move from the language of sacrifice to the obedience of one whose ears God has opened. Verse 7 is completed by verse 8, where the speaker delights to do God's will and has God's law within his heart. The psalm soon turns outward in public testimony, then inward again in a plea for mercy amid overwhelming trouble.
What Does Psalms 40:7 Mean?
"Then said I" presents a response that follows God's gracious dealing. The words "Lo, I come" are brief and direct, as though the speaker has stepped forward in readiness before God. Coming in this setting is more than arriving at a place. It expresses personal availability for the will of the LORD. The final clause, "in the volume of the book it is written of me," places that response within God's written testimony. David recognizes that God's instruction addresses a real person and a real calling. The verse therefore holds together God's prior revelation and the speaker's willing answer. The next verse supplies the central content of that answer: delight in doing God's will.
The surrounding verses give this statement its shape. Verse 6 speaks of sacrifice, offering, burnt offering, and sin offering, all given by God within Israel's worship. Verses 7 and 8 show that such worship reaches toward a listening and obedient life. David comes to God with opened ears, a heart taught by God's law, and a desire to carry out His will. This is not a rejection of the ordinances named in verse 6; the psalm presses toward the inward readiness God seeks in those who draw near to Him. The written book is therefore living instruction. It forms the worshipper's response, public witness, and later plea for preservation.
The New Testament receives Psalm 40:6-8 as bearing a profound witness to Christ's coming and obedience. Hebrews applies the psalm to the Son entering the world and fulfilling the will of God through His offered body. That use does not erase the psalm's voice as David's prayer and confession. It shows that David's language reaches its fullest realization in Christ, whose coming, obedience, and self-offering perfectly accord with the Father's purpose. When we read this verse in that larger light, "Lo, I come" becomes a fitting expression of the faithful Son's readiness. It also invites us to receive God's word as a call to faithful, willing obedience under His mercy.

Where Psalms 40:7 Echoes in Scripture
Hebrews 10:5 draws on Psalm 40:6-8 when it speaks of Christ coming into the world to do God's will. The wording in Hebrews follows the Greek form of the psalm at one point, so readers will notice a difference from the KJV wording of Psalm 40:6. Its central use is clear: Christ's obedience and His offered body fulfill the purpose toward which the psalm's language points. See Hebrews 10:5.
How to Apply Psalms 40:7 Today
This verse gives us language for approaching God's will with honesty and readiness. We may come to Scripture asking where its instruction meets the actual duties, relationships, wounds, and responsibilities before us. The psalm does not picture obedience as detached performance. It grows from ears opened by God, a heart formed by His law, and gratitude for His rescue. In seasons when our path is unclear, we can begin with the light already given. Prayer, careful reading, repentance, service, and public faithfulness are concrete ways of saying, "Lo, I come" before the next detail is known.
