1 John 2:18-23

18 Little children, these are the end times, and as you heard that the Antichrist is coming, even now many antichrists have arisen. By this we know that it is the end times.  19 They went out from us, but they didn't belong to us; for if they had belonged to us, they would have continued with us. But they left, that they might be revealed that none of them belong to us.  20 You have an anointing from the Holy One, and you know the truth.  21 I have not written to you because you don't know the truth, but because you know it, and because no lie is of the truth.  22 Who is the liar but he who denies that Jesus is the Christ? This is the Antichrist, he who denies the Father and the Son.  23 Whoever denies the Son, the same doesn't have the Father. He who confesses the Son has the Father also.
