Acts 2:39

36 For this reason, let all Israel be certain that this Jesus, whom you put to death on the cross, God has made Lord and Christ.

37 Now when these words came to their ears their hearts were troubled, and they said to Peter and the other Apostles, Brothers, what are we to do?

38 And Peter said, Let your hearts be changed, every one of you, and have baptism in the name of Jesus Christ, for the forgiveness of your sins; and you will have the Holy Spirit given to you.

39 For the word of God is for you and for your children and for all those who are far off, even all those who may be marked out by the Lord our God.

40 And with more such words he gave his witness, offering them salvation and saying, Come out from this evil generation.

41 Then those who gave hearing to his words had baptism: and about three thousand souls were joined to them that day.

42 And they kept their attention fixed on the Apostles' teaching and were united together in the taking of broken bread and in prayer.
