After Paul did some evangelistic work on the island of Crete, the Lord moved him on, so that he had to leave some things unfinished but not unattended. As Paul was filled with the Spirit of God to press on in his mission, he was not content to leave things out of order. He had a reliable man to leave behind for the work of God yet to be done in establishing order and appointing elders for the health of the Cretan churches. And this is essential for the health of our churches.
