1 John 2:18-22

18Children, it is the last hour, and just as you heard that the antichrist is coming, so now many antichrists have appeared. We know from this that it is the last hour.

19They went out from us, but they did not really belong to us, because if they had belonged to us, they would have remained with us. But they went out from us to demonstrate that all of them do not belong to us.

20Nevertheless you have an anointing from the Holy One, and you all know.

21I have not written to you that you do not know the truth, but that you do know it, and that no lie is of the truth.

22Who is the liar but the person who denies that Jesus is the Christ? This one is the antichrist: the person who denies the Father and the Son.
