We briefly describe something about what Paul encountered. First, we can see the change of Paul that occurred after the miracle of his seeing a light from heaven flashing around him . Through Ananias, Jesus told him, “for I will show him how much he must suffer for My name’s sake.”  Despite that, Paul still chose to follow Jesus until death. After he saw the big light, he immediately chose to preach Gospel by his old self, and a result “his disciples took him by night and let him down through an opening in the wall, lowering him in a large basket.”  Likely, he went to Arabia for three years, and became an apostle through revelation .
After that, Barnabas found Paul and introduced him to the church of Antioch, and preached the Gospel effectively . Holy Spirit then leads him to the first evangelical trip , and there are three trips in total . Even though he suffered because of strong suppression, he didn’t care for his own life in order to preach for the Lord . He has the life to continue praying and singing hymns of praise to God even in jail . In order to stand for the truth, he even scolded Peter . Holy Spirit also through him to fill others . He could even revive a dead .
He was forced to appeal to Caesar , and it was decided that he would sail for Italy . As a result, he encountered a shipwreck, but an angel of the God appeared to him to ensure him in advance to not be afraid of what will happen . Eventually, he arrived Rome . Even in jail in Rome, he still preached the Gospel . The four books he wrote when jailed benefited so many.
