The elder [of the church addresses this letter] to the beloved and esteemed Gaius, whom I love in truth.

I wrote something to the church; but Diotrephes, who loves to put himself first, does not accept what we say and refuses to recognize my authority.

For this reason, if I come, I will call attention to what he is doing, unjustly accusing us with wicked words and unjustified charges. And not satisfied with this, he refuses to receive the [missionary] brothers himself, and also forbids those who want to [welcome them] and puts them out of the church.

Beloved, do not imitate what is evil, but [imitate] what is good. The one who practices good [exhibiting godly character, moral courage and personal integrity] is of God; the one who practices [or permits or tolerates] evil has not seen God [he has no personal experience with Him and does not know Him at all].
