3 John 1:9-12 - Diotrephes And Demetrius
9 I wrote something to the church, but Diotrephes, who wants to be first [among] them, does not acknowledge us. 10 Therefore, if I come, I will call attention to {the deeds he is doing}, disparaging us with evil words. And not being content with these, he does not receive the brothers himself, and he hinders those wanting [to do so] and throws [them] out of the church.
11 Dear friend, do not imitate [what is] evil, but [what is] good. The one who does good is of God; the one who does evil has not seen God. 12 Demetrius has been testified to by all, even by the truth itself. And we also testify [to him], and you know that our testimony is true.
