1 John 2:18-23
Little children, it is the last hour; and as you have heard that the Antichrist is coming, even now many antichrists have come, by which 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 would have continued with us; but they went out that they might be made manifest, that none of them were of us. [20] But you have an anointing from the Holy One, and you know all things. [21] I have not written to you because you do not know the truth, but because you know it, and that no lie is of the truth. [22] Who is a liar but he who denies that Jesus is the Christ? He is antichrist who denies the Father and the Son. [23] Whoever denies the Son does not have the Father either; he who acknowledges the Son has the Father also.
