3 John 1:3-8

For I rejoiced greatly, when brethren came and bare witness unto thy truth, even as thou walkest in truth. Greater joy have I none than this, to hear of my children walking in the truth. Beloved, thou doest a faithful work in whatsoever thou doest toward them that are brethren and strangers withal; who bare witness to thy love before the church: whom thou wilt do well to set forward on their journey worthily of God: because that for the sake of the Name they went forth, taking nothing of the Gentiles. We therefore ought to welcome such, that we may be fellow-workers for the truth.
