The elder unto the wellbeloved Gaius, whom I love in the truth.

For I rejoiced greatly, when the brethren came and testified of the truth that is in thee, even as thou walkest in the truth.

I have no greater joy than to hear that my children walk in truth.

We therefore ought to receive such, that we might be fellowhelpers to the truth.

Demetrius hath good report of all men, and of the truth itself: yea, and we also bear record; and ye know that our record is true.
