Acts 9:1 Then Saul, still breathing threats and murder against the disciples of the Lord, went to the high priest
Do you know anyone who is so violently against the church? I have known a few people who have been verbally abusive and aggressive toward the church, but not going out of their way to persecute the church!
Even when faced with threats like these, the disciples continued to preach the gospel – admittedly not in front of Saul because that would have been a bit silly.
God was the One who was watching and waiting for Saul; waiting for the right moment to touch his heart.
