Acts 2:36-41

36Let all the house of Israel therefore know for certain that God has made him both Lord and Christ, this Jesus whom you crucified.” 37Now when they heard this they were cut to the heart, and said to Peter and the rest of the apostles, “Brothers, what shall we do?” 38And Peter said to them, “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit. 39For the promise is for you and for your children and for all who are far off, everyone whom the Lord our God calls to himself.” 40And with many other words he bore witness and continued to exhort them, saying, “Save yourselves from this crooked generation.” 41So those who received his word were baptized, and there were added that day about three thousand souls.
