Paul, the greatest and most successful missionary the world has ever known, did not become a pastor. He traveled, preached, won converts, organized churches, placed them under native leadership, and passed on. He did not attempt to change the manners and customs of the people. The gospel, where necessary, did that. He placed responsibility upon the natives themselves, made the churches he founded self-supporting and self-propagating, and that from the very first. He founded no colleges, built no hospitals and erected no church buildings. The natives provided for their own needs.”
