1 John 2:18-27 - Departure Of The False Teachers
18 Young children, it is the last period. And as you have heard that the antichrist comes, so, now, there are many antichrists; whence you know that it is the last period. 19 They went away from us, but they were not of us. For, if they had been of us, they would have abode with us; but they went away, that they might be made manifest that they were not of us.
20 But you have an unction 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 that no lie is of the truth. 22 Who is a liar, if not he who denies that Jesus is the Christ? He is the antichrist who denies the Father and the Son. 23 Whoever denies the Son, does not acknowledge the Father.
24 Therefore, let what you have heard from the beginning abide in you. If what you have heard from the beginning, abide in you; you also shall abide in the Son, and in the Father: 25 and this is the promise which he has promised to us, even eternal life. 26 These things I have written to you, concerning them who deceive you;
27 but the unction which you have received from him abides in you; and you have no need that any one should teach you, unless the same unction teaches you concerning all things, and is truth, and is no lie: and as it has taught you, you will abide in him.
