“And he doeth great wonders, so that he maketh fire come down from heaven on the earth in the sight of men,” (Rev 13:13 KJV)
The false prophet will perform signs and wonders, which will be counterfeit miracles by the power of Satan. He will use these false miracles to deceive the people into following him and the antichrist. He will get this power from Satan, which is something the false prophets of Baal were not able to do.
“36 And it came to pass at the time of the offering of the evening sacrifice, that Elijah the prophet came near, and said, LORD God of Abraham, Isaac, and of Israel, let it be known this day that thou art God in Israel, and that I am thy servant, and that I have done all these things at thy word.
37 Hear me, O LORD, hear me, that this people may know that thou art the LORD God, and that thou hast turned their heart back again.
38 Then the fire of the LORD fell, and consumed the burnt sacrifice, and the wood, and the stones, and the dust, and licked up the water that was in the trench.”
(1Ki 18:36-38 KJV)
