God blessed me with a dramatic conversion. I never had a moment’s doubt that he saved me and changed my heart. On the road to Damascus, the risen Jesus changed Saul’s heart. Saul went from killing Christians to “preaching boldly in the name of the Lord.” When I pray, I try not to ask God to solve my problems. I ask him, if it’s his will, to change my heart.

 And when he had come to Jerusalem, he attempted to join the disciples. And they were all afraid of him, for they did not believe that he was a disciple. But Barnabas took him and brought him to the apostles and declared to them how on the road he had seen the Lord, who spoke to him, and how at Damascus he had preached boldly in the name of Jesus. So he went in and out among them at Jerusalem, preaching boldly in the name of the Lord. And he spoke and disputed against the Hellenists. But they were seeking to kill him. And when the brothers learned this, they brought him down to Caesarea and sent him off to Tarsus. So the church throughout all Judea and Galilee and Samaria had peace and was being built up. And walking in the fear of the Lord and in the comfort of the Holy Spirit, it multiplied.
