Acts 9:20-31; Gal. 1:11-19
Repentance, which is a change of heart along with a change of actions, is one of the requirements for salvation. One of the greatest examples of repentance ever recorded was found in Saul. Soon after his conversion, he went to Arabia for a period of time and received divine instructions through the revelation of Jesus regarding his mission to preach the gospel.
After being taught the gospel more fully, Saul returned to Damascus. His mission of binding followers of Christ and taking them to Jerusalem was reversed and he began to preach that the Christ is indeed the Son of God.
Saul’s change of life placed him in the same danger that he had imposed on the believers earlier. The Jews plotted to kill him, but when he found out about it, the disciples let him down the wall of the city in a basket by night and he escaped and returned to Jerusalem after an absence of more than three years.
After returning to Jerusalem, Saul attempted to join the disciples, but they were afraid of him. Barnabas, one of the early leaders of the church took him to the apostles and explained his conversion to them.
Saul preached boldly in the temple for a few days, but his life was once again in danger. Jesus appeared to him in a trance and instructed him to leave and go preach to the Gentiles. After being in Jerusalem and with Peter only fifteen days, the disciples helped him escape to his hometown of Tarsus.
While away from Jerusalem, Saul did not remain idle. He went into the regions of Syria and Cilicia preaching and establishing churches during the next several years.
