Acts 8:1-3 And Saul approved of their killing him. On that day a great persecution broke out against the church in Jerusalem, and all except the apostles were scattered throughout Judea and Samaria. Godly men buried Stephen and mourned deeply for him. But Saul began to destroy the church. Going from house to house, he dragged off both men and women and put them in prison.
If God can change a man like Saul, it is possible for Him to change anyone, including me.
