In these passages is the account of Saul continuing to persecute the churches. As he was traveling to Damascus to arrest Christians there, a great light surrounded him.
Saul fell from his horse and was completely blind. Then the voice of Jesus said, “Saul, Saul, why are you persecuting me?” Jesus identified Himself to Saul and told Saul to go to the home of Judas in Damascus. Saul was blind for three days and did not eat or drink anything.
Jesus then instructed a disciple, Ananias, to go to Judas’ house and lay his hands on Saul, so that Saul would regain his sight. Saul regained his sight and was converted to be a disciple of Jesus Christ. Saul was chosen by God to preach the Gospel to the Gentiles.
Saul was well prepared academically for this job because Saul knew the Scriptures extremely well. He therefore could teach others using the prophecies in the Scriptures that pointed to Jesus.
There are over 300 prophecies in the Old Testament that have been or will be fulfilled in Jesus. Saul could instantly recall these prophecies when he preached to others.
This account illustrates to me that we must be well prepared to be used by God in a significant way. This preparation comes from personal effort and diligence in reading and studying the Bible.
