“Be it known unto you therefore, men and brethren, that through this man is preached unto you the forgiveness of sins:”
King James Version (KJV)
13:36 David, having served the will of God in his generation, fell asleep - So his service extended not itself beyond the bounds of the common age of man: but the service of the Messiah to all generations, as his kingdom to all ages. Served the will of God - Why art thou here thou who art yet in the world? Is it not that thou also mayest serve the will of God? Art thou serving it now? Doing all his will? And was added to his fathers - Not only in body. This expression refers to the soul also, and supposes the immortality of it.
13:39 Every one that believeth is justified from all things - Has the actual forgiveness of all his sins, at the very time of his believing; from which ye could not be justified - Not only ye cannot now; but ye never could. For it afforded no expiation for presumptuous sins. By the law of Moses - The whole Mosaic institution! The division of the law into moral and ceremonial was not so common among the Jews, as it is among us. Nor does the apostle here consider it at all: but Moses and Christ are opposed to each other.
13:40 Beware - A weighty and seasonable admonition. No reproof is as yet added to it.
Ac 13:38 Through this man. The risen Savior. The forgiveness of sins. Only through Christ does God offer pardon. See Ac 4:12 Ro 3:25 8:1-4.
