3 John 1:9-11

9I wrote unto the church: but Diotrephes, who loveth to have the preeminence among them, receiveth us not.

10Wherefore, if I come, I will remember his deeds which he doeth, prating against us with malicious words: and not content therewith, neither doth he himself receive the brethren, and forbiddeth them that would, and casteth them out of the church.

11Beloved, follow not that which is evil, but that which is good. He that doeth good is of God: but he that doeth evil hath not seen God.
