“Immediately he preached the Christ in the synagogues, that He is the Son of God” (Acts 9:20 NKJV).

Saul the persecutor became Paul the preacher. Within days of his Damascus road experience with Jesus, Saul was preaching Christ in the synagogues. His passion for killing Christians had been replaced with a passion for making them. Why? Because he had encountered the risen Christ and believed. And he wanted everyone to know what Christ had done for them.
 
Are all believers immediately called to making disciples for Jesus? Paul certainly thought so.
