Now when they heard this they were cut to the heart, and said to Peter and the rest of the apostles, "Brethren, what shall we do?"
And 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 shall receive the gift of the Holy Spirit.
For the promise is to you and to your children and to all that are far off, every one whom the Lord our God calls to him."
And he testified with many other words and exhorted them, saying, "Save yourselves from this crooked generation."
So those who received his word were baptized, and there were added that day about three thousand souls.
And they devoted themselves to the apostles' teaching and fellowship, to the breaking of bread and the prayers.
And fear came upon every soul; and many wonders and signs were done through the apostles.
And all who believed were together and had all things in common;
and they sold their possessions and goods and distributed them to all, as any had need.
And day by day, attending the temple together and breaking bread in their homes, they partook of food with glad and generous hearts,
praising God and having favor with all the people. And the Lord added to their number day by day those who were being saved.
