2nd John 1:9

6 and this is the love, that we may walk according to His commands; this is the command, even as ye did hear from the beginning, that in it ye may walk,

7 because many leading astray did enter into the world, who are not confessing Jesus Christ coming in flesh; this one is he who is leading astray, and the antichrist.

8 See to yourselves that ye may not lose the things that we wrought, but a full reward may receive;

9 every one who is transgressing, and is not remaining in the teaching of the Christ, hath not God; he who is remaining in the teaching of the Christ, this one hath both the Father and the Son;

10 if any one doth come unto you, and this teaching doth not bear, receive him not into the house, and say not to him, `Hail!`

11 for he who is saying to him, `Hail,` hath fellowship with his evil works.

12 Many things having to write to you, I did not intend through paper and ink, but I hope to come unto you, and speak mouth to mouth, that our joy may be full;
