'Miracles' in the Bible

He performs great signs (awe-inspiring acts), even making fire fall from the sky to the earth, right before peoples’ eyes.

And he deceives those [unconverted ones] who inhabit the earth [into believing him] because of the signs which he is given [by Satan] to perform in the presence of the [first] beast, telling those who inhabit the earth to make an image to the beast who was wounded [fatally] by the sword and has come back to life.

for they are [actually] the spirits of demons, performing [miraculous] signs. And they go out to the kings of the entire inhabited earth, to gather them together for the war of the great day of God, the Almighty.

And the beast (Antichrist) was seized and overpowered, and with him the false prophet who, in his presence, had performed [amazing] signs by which he deceived those who had received the mark of the beast and those who worshiped his image; these two were hurled alive into the lake of fire which blazes with brimstone.
