13:32-37 The resurrection of Christ was the great proof of his being the Son of God. It was not possible he should be held by death, because he was the Son of God, and therefore had life in himself, which he could not lay down but with a design to take it again. The sure mercies of David are that everlasting life, of which the resurrection was a sure pledge; and the blessings of redemption in Christ are a certain earnest, even in this world. David was a great blessing to the age wherein he lived. We were not born for ourselves, but there are those living around us, to whom we must study to be serviceable. Yet here is the difference; Christ was to serve all generations. May we look to Him who is declared to be the Son of God by his resurrection from the dead, that by faith in him we may walk with God, and serve our generation according to his will; and when death comes, may we fall asleep in him, with a joyful hope of a blessed resurrection.

See on Joh 1:14. But how do these words prove the resurrection of Christ? "They presuppose it; for since an eternal kingdom was promised to David, the Ruler of this kingdom could not remain under the power of death. But to strengthen the indefinite prediction by one more definite, the apostle adduces Ps 16:10, of which Peter had given the same explanation (see on Ac 2:27; Ac 2:30, 31), both apostles denying the possibility of its proper reference to David" [Olshausen].
