1 John 2:18-27 - Departure Of The False Teachers
18 Little children, it is the last time: and as ye have heard that Antichrist cometh, so even now there are many Antichrists, whereby 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, that they might be made manifest, that they were not all of us.
20 But ye have an anointing from the Holy one, and know all things. 21 I have not written to you, because ye know not the truth; but because ye know it, and that no lie is of the truth. 22 Who is that liar, but he that denieth that Jesus is the Christ? He is Antichrist who denieth the Father and the Son. 23 Whosoever denieth the Son, he hath not the Father: he that acknowledgeth the Son, hath the Father also.
24 Therefore let that abide in you which ye heard from the beginning: if that which ye heard from the beginning abide in you, ye also shall abide in the Son and in the Father. 25 And this is the promise which he hath promised us, eternal life. 26 These things have I written to you, concerning them that seduce you.
27 But the anointing which ye have received of him abideth in you, and ye need not that any should teach you, save as the same anointing teacheth you of all things, and is truth, and is no lie; and as it hath taught you, ye shall abide in them.
