It's not about believing or not believing. I'm just after an understanding as to why.
Since you asked, here it is,
I cannot answer the 'Why', because that question links all the way upto, why we are here, so it really is understandable in the bigger context for someone who is well aware of the history of the world, and the history of all divine religions.
The divine books and all the Prophets used to inform their people of the anti- Christ . I think there is some thing about him in christianity too, but i'm not too sure as to what extent. Briefly, he is going to be the World leader ,of the New world order and He will only come when some of the signs have occurred which have been described and predicted.
He's supposed to be a very powerful leader, and shall have immense powers, so much so, that out of arrogance of his powers, he shall claim to be God. His powers will be quite impressive for those who do not relate to the concept of God and don't believe in heaven/hell, or any such thing.
His (one of the) prime recognition is the one eye, and that one eye symbol is pretty much seen Everywhere these days. Also, the one eye symbol (in an assortment) is the symbol of some of the most rich , powerful secret cults of the world today, you'd probably know, but if you do not, you can search for it.
For a brief period of time,(not specified) he shall seem invincible. But then, Somebody will come and strike him down , exposing his fallacy.
In Islam, It is said, that It is going to be The resurrected Jesus Christ pbuh,( Prophet Eesa Alay salam) who is going to strike him down. I wanted to know, what are the christians beliefs?( apart from other beliefs)
