3 John 1:4
I have no greater joy than to hear that my children walk in truth.
I have no greater joy,.... Nothing that causes greater joy. The Vulgate Latin version reads "grace" or "thanks"; and then the sense is, that he had nothing to be more thankful for:
than to hear that my children walk in truth; meaning his spiritual children, those whose conversion he had been the instrument of; and among these it seems Gaius was one.
