Why the Church began in Acts 9 not at the cross or in Acts 2 - Marianne Manley

The Church, the body of Christ began in Acts 9, not at the cross or in Acts 2,
because of a one-year extension of mercy by God for Israel to believe that
Jesus Christ of Nazareth is Israel's Messiah (Luke 13:6-9, 23:34).
This was a bonus year on top of the 490 years prophesied to Daniel (Dan. 9:24-27).
God is spending 7,000 years to find the believers that will live in heaven and on earth.
The gospel of our salvation during the dispensation of grace is to believe that:
Jesus Christ died for our sins, was buried, and rose again the third day according to the scriptures (1 Corinthians 15:3, 4).
