"Christ says that just before the end “there shall arise false Christ’s,
and false prophets, and shall show great signs and wonders; insomuch
that, if it were possible, they shall deceive the very elect” (Matt.
24:24).
And Paul says that just before the coming of Christ, Satan will
work “with all power and signs and lying wonders, and with all
deceivableness of unrighteousness” (2 Thess. 2:9,10).
---The miracles,
which Satan works, are intended to deceive, and 
since they almost
deceive even the saints of God, it is evident that they have the
appearance of good. In order to capture professed Christians, Satan is
going to profess to be Christ, and he must therefore counterfeit as far
as possible the work of Christ.
---Sometimes men wonder why the Lord should allow Satan to deceive people.
*He doesn’t allow him to deceive anyone who doesn’t want to be deceived.
Only those who receive not the love of the truth, will fall under
Satan’s wiles.
*No matter what garb Satan or his angels may assume, they
can always be detected by comparing their words with the plain
declarations of the Bible."
