And we declare unto you glad tidings, how that the promise which was made unto the fathers,

People's New Testament

13:27-37 For they that dwell at Jerusalem, etc. Paul now recapitulates the facts of the Gospel, viz: (1) Christ rejected by the rulers; (2) the Scriptures that they read every Sabbath fulfilled by condemning him; (3) the demand upon Pilate to slay him, when he had declared there was no cause of death; (4) the Scriptures fulfilled in his death; (5) the abundantly attested resurrection; (6) he declares that the promise made the fathers was now fulfilled to their children. See, for example, Ge 12:3 22:18.

Matthew Henry's Concise Commentary

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.
