The Church, the body of Christ, did not start in Acts 2 (WIP)

On the Day of Pentecost, God gave His Holy Spirit to those with Peter and the eleven (the 120 noted in Acts 1:15).
Peter quoted the prophet Joel that God would pour His Spirit upon all flesh in the last days, but Peter only addressed the Jewish nation, not all flesh.
1. Gentiles were not included in Peter’s message (Acts 2:14, 22-23, 29, 39).
2. Peter understood that Jews had to come first according to Jesus’ instruction, “And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem” (Lk 24:47, Acts 1:8).
Pentecost was the beginning of the fulfillment of God’s promise of the indwelling Holy Spirit and Peter addressed the Jewish people to repent from having crucified their Messiah, be baptized, and believe that Jesus was the Christ (Acts 2:36-38).
1. If they would have, they would have received the Holy Spirit.
2. Only after Israel repented could the nation fulfill the spiritual aspects of the Abrahamic Covenant to be a blessing to gentiles (Zech 8:20-23).
3. The Jewish people will one day obey God once God enables them through the power of the indwelling Holy Spirit (the New Covenant).
