In fact, the Bible tells us that one day the Antichrist will set himself up in God's Temple and proclaim himself to be God. Just read what it says in 2 Thessalonians 2:3-4.....

Don't let anyone deceive you in any way, for (that day will not come) until the rebellion occurs and the man of lawlessness is revealed, the man doomed to destruction. He will oppose and will exalt himself over everything that is called God or is worshiped, so that he sets himself up in God's temple (Third Temple), proclaiming himself to be God.   http://www.youtube.com/watch?v=f6K-cld3X4Q&feature=related
