Your not familiar with the "beast" of the Revelation?
Revelation 13:13-14,/b>
13 He performs great signs, so that he even makes fire come down from heaven on the earth in the sight of men. 14 And he deceives those[e] who dwell on the earth by those signs which he was granted to do in the sight of the beast, telling those who dwell on the earth to make an image to the beast who was wounded by the sword and lived.
But are you not familiar with the Scripture in which Jesus is challenged, when he performs his healings and exorcisms, with using Satan to cast out Satan?
Are you unfamiliar with Jesus' response?
One would gather from this that there is something in the healing function which differs from other signs.
Well, I am not surprised to read you think the Devil can perform miracles
