Acts 9:4 Then he fell to the ground, and heard a voice saying to him, “Saul, Saul, why are you persecuting Me?”
Saul was a man of God. What he did not do was make the connection between Christ and God because he was too tied up in carrying out the punishment for breaking the rules.
These were no longer the rules God laid out but a perversion of those commands given to Moses to suit mankind, or at least the Jews.
Don’t wait for God to have to shout at you! Stop and meditate on God’s Word and see how much Christ has done for you already!
