Be it known unto you therefore, men and brethren, that through this man is preached unto you the forgiveness of sins: Be it known unto you, therefore - This is the legitimate conclusion: seeing the word of God is true, and he has promised an endless succession to the seed of David; seeing David and all his family have failed in reference to the political kingdom, a spiritual kingdom and a spiritual succession must be intended, that the sure covenant and all its blessings may be continued. Again: seeing the person by whom this is to be done is to see no corruption; - seeing David has died, and has seen (fallen under the power of) corruption; - seeing Jesus the Christ has wrought all the miracles which the prophets said he should work; - seeing he has suffered all the indignities which your prophets said he must suffer; - seeing after his death he has most incontestably risen again from the dead, and has not fallen under the power of corruption, - then he must be the very person in whom all the predictions are fulfilled, and the person through whom all the blessings of the covenant must come.
Through this man is preached unto you the forgiveness of sins - See the notes on Acts 5:30, Acts 5:31. Remission of sins, the removal of the power, guilt, and pollution of sin comes alone through this man, whom ye crucified, and who is risen from the dead.
