2 John 1:7 ASV

⁵  And now I beseech thee, lady, not as though I wrote to thee a new commandment, but that which we had from the beginning, that we love one another.

⁶  And this is love, that we should walk after his commandments. This is the commandment, even as ye heard from the beginning, that ye should walk in it.

⁷  For many deceivers are gone forth into the world, 'even' they that confess not that Jesus Christ cometh in the flesh. This is the deceiver and the antichrist.

⁸  Look to yourselves, that ye lose not the things which we have wrought, but that ye receive a full reward.

⁹  Whosoever goeth onward and abideth not in the teaching of Christ, hath not God: he that abideth in the teaching, the same hath both the Father and the Son.
