6 Doing something for you, bringing something to you - that's not what you're after. Being religious, acting pious - that's not what you're asking for. You've opened my ears so I can listen. 7 So I answered, "I'm coming. I read in your letter what you wrote about me, 8 And I'm coming to the party you're throwing for me." That's when God's Word entered my life, became part of my very being.
Matthew Henry's Commentary on Psalm 40:6-8
Commentary on Psalm 40:6-10
(Read Psalm 40:6-10)
The psalmist foretells that work of wonder, redemption by our Lord Jesus Christ. The Substance must come, which is Christ, who must bring that glory to God, and that grace to man, which it was impossible the sacrifices should ever do. Observe the setting apart of our Lord Jesus to the work and office of Mediator. In the volume, or roll, of the book it was written of him. In the close rolls of the Divine decrees and counsel, the covenant of redemption was recorded. Also, in all the volumes of the Old Testament something was written of him, John 19:28. Now the purchase of our salvation is made, the proclamation is sent forth, calling us to come and accept it. It was preached freely and openly. Whoever undertook to preach the gospel of Christ, would be under great temptation to conceal it; but Christ, and those he calls to that work, are carried on in it. May we believe his testimony, trust his promise, and submit to his authority.
