2 John 1:5-7

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

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

7For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh. This is a deceiver and an antichrist.
