Acts 2:37-39

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