1 John 2:18-27 - Departure Of The False Teachers
18 Young children, it is the last hour: and as ye have heard that antichrist comes, and now many antichrists have come; whence we know that 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 had remained with us, but, that they might be manifested, that they are not all of us.
20 And 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 a liar if not he denying that Jesus is the Christ? He is antichrist, denying the Father and the Son. 23 Every one denying the Son, neither has the Father: he acknowledging the Son, has also the Father.
24 What therefore ye have heard from the beginning, let remain in you. If it remain in you what ye heard from the beginning, ye also shall remain in the Son, and in the Father. 25 And this is the promise which he promised us, eternal life. 26 These I wrote to you concerning them deceiving you.
27 And the anointing which ye received from him remains in you, and ye have no need that any teach you: but as the same anointing teaches you of all things, and is true, and is no lie, and as it taught you, ye shall remain in him.
