Acts 2:37-39

37Now when they heard this, they were pricked in their heart, and said to Peter and to the rest of the apostles, Men, brethren, what shall we do? 38Then Peter said to them, Repent ye, and each one of you be baptized in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Spirit. 39For the promise is to you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.
