1 John 2:18-27 - Departure Of The False Teachers
18 My children, this is the last hour, and as you have heard that an antichrist was coming, and now many antichrists are already risen, whence we may know that it is the last hour. 19 They came forth from us, but they did not belong to us. If they had belonged to us they would certainly have remained with us, but they went out that they might be manifest that they all are not of us.
20 Now you have an anointing from the Holy One, and you know all things. 21 I am not writing to you because you do not know the truth, but because you do know it, and know that no lie is of the truth. 22 Who is the liar if not the man who denies that Jesus is the Christ? This is the Antichrist, even he who disowns the Father and the Son. 23 Whoever denies the Son, the same has not the Father; but he who confesses the Son has the Father also. As for you, let what you have heard from the beginning abide in you.
24 If what you have heard from the beginning is abiding in you, you also will ever abide in the Son and in the Father. 25 And this is the promise which he has promised to us even life eternal. 26 I have written this to you concerning those who would lead you astray.
27 As to you, the unction you received from him remains ever in you, and you need no teaching from any one. But since his unction teaches you concerning all things and is true, and is no lie, abide continually in him, as it has taught you to do.
