3 John 1:9-11

9I wrote to the church, but Diotrephes, who loves to have the preeminence among them, does not receive us.

10Therefore, if I come, I will call to mind his deeds which he does, prating against us with malicious words. And not content with that, he himself does not receive the brethren, and forbids those who wish to, putting them out of the church.

11Beloved, do not imitate what is evil, but what is good. He who does good is of God, but he who does evil has not seen God.
