Daniel 2 shows us the statue which teaches us that the Holy Roman Empire will be the final world government. The Antichrist will come out of this.
Daniel 7 tells us that the Antichrist will have a mouth speaking great words. The Antichrist is going to be an eloquent speaker and will create an impact with his words.It also tells us that he will be more stout than his fellows. So even his appearance will distinguish him. He will come up among ten kings and uproot three of them.
We have more details given in Daniel 8.
And in the latter time of their kingdom, when the transgressors are come to the full, a king of fierce countenance, and understanding dark sentences, shall stand up. And his power shall be mighty, but not by his own power: and he shall destroy wonderfully, and shall prosper, and practise, and shall destroy the mighty and the holy people. And through his policy also he shall cause craft to prosper in his hand; and he shall magnify himself in his heart, and by peace shall destroy many: he shall also stand up against the Prince of princes; but he shall be broken without hand. (Daniel 8:23-25 KJV)
Destroys by Peace
Earlier in this chapter it says he will cast the truth to the ground. He will not stand on Biblical principles and he will ridicule them.
Daniel 11 also tells us a lot about the Antichrist, who is the king of the north, but in particular it tells us that he will not regard the desire of women. Many have said this means he will be a homosexual or endorse homosexuality. However it does not say he will not desire women it says he won’t regard the desire of women. Women want to have children. So the Antichrist will probably support abortion and try to enforce laws that prevent women from having children.
Daniel 9:27 tells us something very key about the Antichrist. We learn that he shall confirm the covenant with many. This is referring to the covenant God made with Abraham in Genesis 15:18. So essentially the Antichrist will establish the borders of Israel and create a sharing arrangement on the Temple Mount. Keep in mind this will be a group effort but the Antichrist will be in that group.
Then in multiple passages we learn what happens 3 1/2 years later. The Antichrist will cause the animal sacrifices to cease and fulfill the abomination of desolation. This is when he will claim to be God and speak against God. This is when we will know without a shadow of a doubt who the Antichrist is.
