Saul was on the road to Damascus (Acts 9). He was going there to arrest Christians and take them back to Jerusalem for punishment. Jesus appeared to Saul and blinded him. Saul was told to go to Damascus; it was there that Saul was to be told what Jesus required him to do.
Jesus also appeared to Ananias in a vision. He was a Christian who lived in Damascus. Jesus told him to go to a house on Straight Street. This was one of the main roads in Damascus. He was told that Saul was in that house. The house was owned by a man named Judas. It is highly likely that Judas was not a Christian. The men who had been with Saul would have probably taken him to their contact in Damascus. The fact that the Lord did not appear to Judas is a good indication that Judas was not a Christian. We are not told anything else about Judas. We have no idea if Saul’s conversion had an impact on Judas. Yet, the healing of Saul’s blindness and his baptism into Jesus must have made some kind of impression on him.
We hope that Judas was converted. Jesus wants all people to be Christians. It is truly sad if Judas did not become a Christian. He would have seen with his own eyes and heard with his own ears what Jesus was doing with and through Ananias and Saul.
