3 John:3-8

3 For I rejoiced greatly, when brothers came and testified about your truth, even as you walk in truth.  4 I have no greater joy than this, to hear about my children walking in truth.

5 Beloved, you do a faithful work in whatever you accomplish for those who are brothers and strangers.  6 They have testified about your love before the assembly. You will do well to send them forward on their journey in a manner worthy of God,  7 because for the sake of the Name they went out, taking nothing from the Gentiles.  8 We therefore ought to receive such, that we may be fellow workers for the truth.
