Neither shall he regard the God of his fathers, nor the desire of women, nor regard any god: for he shall magnify himself above all. Daniel 11:37
That's a lot of mileage out of one verse!
But there shouldn't be any doubt about the identity of the antichrist. The word "antichrist" occurs only four times in the Bible, but those four verses tell us all we need to know.
Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists; whereby we know that it is the last time. 1 John 2:18
Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son. 1 John 2:22
And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world. 1 John 4:3
For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh. This is a deceiver and an antichrist. 2 John 1:7
Whoever denies that Jesus is the Christ is an antichrist. That would include all Jews, gay or straight, along with about 4 billion others. It certainly includes me.
I am a proud member of the antichrist community.
