The Devil also cures.
He does prodigy trough the 2nd beast, his idols and fake prophets. Rev 13:
13- And he doeth great wonders, so that he maketh fire come down from heaven on the earth , in the sight of men, (At the time of Elijah the prophets of Baal (Devil) couldn’t make fire drop from the sky, but after this 2nd beast, they will). And, at the end of Revelation, confirms that the spirit of the evil trinity has the power to cure. Rev.16.
13- And I saw three unclean spirits like frogs [come] out of the mouth of the dragon, and out of the mouth of the beast, and out of the mouth of the false prophet.
14- For they are the spirits of devils, working miracles, [which] go forth unto the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty.
Jesus, speaking of the end, alerts us in Matt. 24:11- And many false prophets shall rise, and

shall deceive many.
24- For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if [it were] possible, they shall deceive the very elect.
The fake prophet the one that tries to look like the real, doesn’t work for faith, but for money, and is in the middle of the church. Jesus alerts us in Matt. 7. 15 to 23:
15- Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves. (In soul).
16- Ye shall know them by their fruits. (...).
Jesus says that at judgment many will be surprised by doom, thinking they were of God for doing many miracles and expel demons. Even those were deceived by the Devil. Matt.
7: 22- Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
