1 John 2 - Antichrists.

18
Children, it is the last hour;* and just as you heard that the antichrist was coming, so now many antichrists have appeared. Thus we know this is the last hour.
19
They went out from us, but they were not really of our number;* if they had been, they would have remained with us. Their desertion shows that none of them was of our number.
20
But you have the anointing that comes from the holy one,* and you all have knowledge.
21
I write to you not because you do not know the truth but because you do, and because every lie is alien to the truth.
22
* Who is the liar? Whoever denies that Jesus is the Christ. Whoever denies the Father and the Son, this is the antichrist.
23
No one who denies the Son has the Father, but whoever confesses the Son has the Father as well.


Revelation 21:8 - But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.
