vs 1-2 speaks of how Saul was persecuting the church because he believed he was doing the right thing

From vs 3 He encountered God and he channelled that zeal into pursuing the interest of God's kingdom.

This is why we must pray for the repentance and conversion of unbelievers, and also preach to them, because they will be a mighty tool in God's kingdom.

Have you prayed for an unsaved soul today?
Have you talked to anyone about Jesus today?
