How does the Antichrist perform miracles during the great tribulation period?


Let's look at several sections of Scripture:
Concerning the coming of our Lord Jesus Christ and our being gathered to him, we ask you, brothers, not to become easily unsettled or alarmed by some prophecy, report or letter supposed to have come from us, saying that the day of the Lord has already come.

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, proclaiming himself to be God... .

The coming of the lawless one will be in accordance with the work of Satan displayed in all kinds of counterfeit miracles, signs and wonders, and in every sort of evil that deceives those who are perishing. They perish because they refused to love the truth and so be saved.

For this reason God sends them a powerful delusion so that they will believe the lie.
(2 Thess. 2:1-4, 9-11 NIV)
Then I saw three evil spirits that looked like frogs; they came out of the mouth of the dragon, out of the mouth of the beast (Antichrist) and out of the mouth of the false prophet. 14 They are spirits of demons performing miraculous signs, and they go out to the kings of the whole world, to gather them for the battle on the great day of God Almighty.
(Rev. 16:13-14 NIV)
The Antichrist will perform miracles, signs, and wonders with the help of the devil and his demon helpers. People on the earth at that time will be so impressed that they will follow the Antichrist.
