1 John 2:18-27 - Departure Of The False Teachers
18 Little children, it is the last time; and as you heard that antichrist is coming, even now many have become anti-christs; whence we know that it is the last time. 19 They went out from us, but they were not of us; for if they had been of us they would have continued with us; but [they went out from us] that they might be manifest that they are not all of us.
20 And you have an anointing from the Holy One, and know all things. 21 I have not written to you because you know not the truth, but because you know it, and because no lie is of the truth. 22 Who is a liar but he that denies that Jesus is the Christ? This is the anti-christ, [the man that] denies the Father and the Son. 23 No one that denies the Son has the Father; he that confesses the Son has the Father also.
24 Let that which you heard from the beginning continue in you. If that which you heard from the beginning continues in you, you also shall continue in the Son and in the Father. 25 And this is the promise which he promised us, the eternal life. 26 I have written these things to you concerning those who deceive you.
27 And the anointing which you received from him continues in you, and you have no need that any one should teach you; but as his anointing teaches you of all things, and is true and is not a lie, even as it has taught you, continue in him.
