1 John 2:18-27 - Departure Of The False Teachers
18 My dear children, it is the last hour; and as ye have heard that antichrist is coming, even now there are many antichrists: by which we know it is the last hour. 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 departed, that they might be made manifest that they are not all of us:
20 though ye have an unction 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 the liar, but he that denieth that Jesus is the Messiah? This man is the antichrist, who denieth the Father and the Son. 23 Every one that denieth the Son, neither doth he hold the Father; but he that acknowledgeth the Son, holdeth the Father also.
24 Let that abide in you therefore which ye have heard from the beginning. If that abide in you which ye heard from the beginning, ye also shall abide in the Son and in the Father. 25 And this is the promise which he hath promised to us, even life eternal. 26 These things have I written unto you concerning those who are leading you astray.
27 But the unction which ye have received from him abideth in you; and ye need not that any person should instruct you. But as the same unction teacheth you concerning all things, and is true, and is no lie; and as it hath taught you, abide in him.
