“And now, brethren, I know that you acted in ignorance, just as your rulers did also. But the things which God announced beforehand by the mouth of all the prophets, that His Christ would suffer, He has thus fulfilled. Therefore repent and return, so that your sins may be wiped away, in order that times of refreshing may come from the presence of the Lord; and that He may send Jesus, the Christ appointed for you, whom heaven must receive until the period of restoration of all things about which God spoke by the mouth of His holy prophets from ancient time. (Acts 3:17-21, NASB)
The text above is a part of Peter’s second recorded sermon, documented by Dr. Luke in his book of Acts. Peter had just healed a lame beggar near the Temple in Jerusalem, and the crowd among them was amazed. “But when Peter saw this, he replied to the people, ‘Men of Israel, why are you amazed at this, or why do you gaze at us, as if by our own power or piety we had made him walk?'” (Acts 3:12) At this, Peter launches into his sermon.
Peter reminds the onlookers that they had traded Jesus for Barabbas, a murderer, and insisted that Jesus be crucified by Pilate. He tells them that Jesus has been raised from the dead, and that their God, the God of Abraham, Isaac, and Jacob, had so glorified this Jesus. Peter then tells them that it is not he who healed the man, but “it is the name of Jesus which has strengthened this man whom you see and know; and the faith which comes through Him has given him this perfect health in the presence of you all.”
We pick up with the passage above. Peter tells the crowd that the prophets foretold of the Messiah’s coming, and that Jesus had fulfilled what was prophesied. Next, he gives advice which is good for us today: “Therefore repent and return, so that your sins may be wiped away, in order that times of refreshing may come from the presence of the Lord; and that He may send Jesus, the Christ appointed for you.”
The word “repent” means to turn from. In today’s slang, we say, “do a 180.” With respect to sin, it means we must turn from it, and not go back. Peter says that when we truly do this, that God will send us His Son Jesus, and we will have “times of refreshing” in our lives.
This is the same Peter, who only weeks before, on the night Jesus was betrayed and led before the Temple authorities, had denied knowing Him. But now, having been filled with the Holy Spirit, Peter was now speaking the truth with no fear. That same power is available to us, if we follow Peter’s advice, to repent of our sins, and to accept Jesus Christ as Savior of our lives!
