1 John 2:18-23 NIV

[18] Dear children, this is the last hour; and as you have heard that the antichrist is coming, even now many antichrists have come. This is how we know it is the last hour. [19] They went out from us, but they did not really belong to us. For if they had belonged to us, they would have remained with us; but their going showed that none of them belonged to us. [20] But you have an anointing from the Holy One, and all of you know the truth. [21] I do not write to you because you do not know the truth, but because you do know it and because no lie comes from the truth. [22] Who is the liar? It is whoever denies that Jesus is the Christ. Such a person is the antichrist—denying the Father and the Son. [23] No one who denies the Son has the Father; whoever acknowledges the Son has the Father also.
