Acts 2:36-47

Therefore let all the house of Israel recognize beyond all doubt that God has made Him both Lord and Christ (Messiah, Anointed)—this Jesus whom you crucified.” Now when they heard this, they were cut to the heart [with remorse and anxiety], and they said to Peter and the rest of the apostles, “Brothers, what are we to do?” And Peter said to them, “Repent [change your old way of thinking, turn from your sinful ways, accept and follow Jesus as the Messiah] and be baptized, each of you, in the name of Jesus Christ for the forgiveness of your sins; and you will receive the gift of the Holy Spirit. For the promise [of the Holy Spirit] is for you and your children and for all who are far away [including the Gentiles], as many as the Lord our God calls to Himself.” [Is 57:19; Joel 2:32] And Peter solemnly testified and continued to admonish and urge them with many more words, saying, “Be saved from this crooked and unjust generation!” So then, those who accepted his message were baptized; and on that day about 3,000 souls were added [to the body of believers]. They were continually and faithfully devoting themselves to the instruction of the apostles, and to fellowship, to eating meals together and to prayers. A sense of awe was felt by everyone, and many wonders and signs (attesting miracles) were taking place through the apostles. And all those who had believed [in Jesus as Savior] were together and had all things in common [considering their possessions to belong to the group as a whole]. And they began selling their property and possessions and were sharing the proceeds with all [the other believers], as anyone had need. Day after day they met in the temple [area] continuing with one mind, and breaking bread in various private homes. They were eating their meals together with joy and generous hearts, praising God continually, and having favor with all the people. And the Lord kept adding to their number daily those who were being saved.
