1 John 2:18-27 - Departure Of The False Teachers
18 My Children, these are the last days. You were told that an Anti-Christ was coming; and many Anti-Christ's have already arisen. By that we know that these are the last days. 19 From us, it is true, they went out, but they had never belonged to us; for, if they had belonged to us, they would have remained among us. They left us that it might be made clear that they do not, any of them, belong to us.
20 You, however, have received consecration from the Holy One. 21 You all know--But I am not writing to you because you do not know the Truth, but because you do know it, and because nothing false can come from the Truth. 22 Who is a liar, if not the man who rejects the truth that Jesus is the Christ? He is the Anti-Christ--The man who rejects the Father and the Son. 23 No one who rejects the Son has found the Father; he who acknowledges the Son has found the Father also.
24 As for you, let what you were told at the first be always in your thoughts. If, then, what you were told at the first is always in your thoughts, you yourselves will maintain your union both with the Son and with the Father. 25 And this is what he himself promised us--The Immortal Life! 26 In writing thus to you, I have in mind those who are trying to mislead you.
27 But you--you still retain in your hears that consecration which you received from the Christ, and are not in need of any one to teach you; but, since his consecration of you teaches you about everything, and since it is a real consecration, and no lie, then, as it has taught you, maintain your union with him.
