"In many places self-supporting missionaries can work successfully. It was as a self-supporting missionary that the apostle Paul labored in spreading the knowledge of Christ throughout the world. While daily teaching the gospel in the great cities of Asia and Europe, he wrought at the trade of a craftsman to sustain himself and his companions".

Mark 9: 38 - 40
9:38 And John answered him, saying, Master, we saw one casting out devils in thy name, and he followeth not us: and we forbad him, because he followeth not us.
9:39 But Jesus said, Forbid him not: for there is no man which shall do a miracle in my name, that can lightly speak evil of me.
9:40 For he that is not against us is on our part.
