3 John 1:10-11 KJV

10 Wherefore , 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.
11 Beloved, 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.
