Apostle Paul left Titus behind on the island of Crete to “ordain elders in every city.” (Titus 1:5) This implies that among the natives of the Island of Crete there were spiritually strong men who were qualified for pastoral office.
History and New Testament principle shows that no one can reach the natives of any place better than the natives themselves.
Many national, cultural and language barriers are broken down. The Lord Jesus told the man who had been possessed with the Legion “Go home to thy friends, and tell them how great things the Lord hath done for thee.” (Mark 5:19) The Gadarenes could not argue with the changed life of one of their own people.
Geronimo wanted to become a Christian after observing the changed lives of his loyal warriors, Chatto and Naiche.
Apostle Paul was Jewish, and God sent him to preach the gospel to the Gentiles. Yet Paul did not seek to pastor Gentile churches long term. Paul’s continual goal in the churches was to “work himself out of a job” by training “faithful men, who shall be able to teach others also.” (2 Timothy 2:2)
