3 John 1:9-12

I wrote somewhat unto the church: but Diotrephes, who loveth to have the preeminence among them, receiveth us not. Therefore, if I come, I will bring to remembrance his works which he doeth, prating against us with wicked words: and not content therewith, neither doth he himself receive the brethren, and them that would he forbiddeth and casteth them out of the church. Beloved, imitate not that which is evil, but that which is good. He that doeth good is of God: he that doeth evil hath not seen God. Demetrius hath the witness of all men, and of the truth itself: yea, we also bear witness; and thou knowest that our witness is true.
