Satan uses the deception of impersonation to deceive many. We must therefore watch out and pray and be on the alert (sober and vigilant) so that we are not deceived (1 Peter 4:7).

For the redemption of mankind from their own sins, God had to manifest himself in the form of a messiah (the “anointed” Christ) and came to the world he created as a human (Philippians 2) and was named Jesus (Matthew 1:21). Jesus, the Only Christ came with a sword (Matthew 10:34) and left peace (John 14:27). When the tip of a sword is placed into the ground, it resembles the shape of a Cross and a sword can divide, just as the Cross divides the righteous (those who have believed in Jesus) and those who have not.
But Satan who has no original idea of his own will bring his own messiah, who is the antichrist. The antichrist will come with a deception of peace and leave behind a sword, destroying many (Daniel 8:25). The antichrist is the antimessiah.

Points to ponder:
We must be aware and beware the adversary (Satan), for Satan will bring the antichrist as the messiah of mankind, who will impersonate Jesus Christ, the Only Lord (Messiah of all mankind). Watch vigilantly and pray always, lest we are caught off-guard. 

Matthew 10:34 (KJV)
34 Think not that I am come to send peace on earth: I came not to send peace, but a sword.

John 14:27 (KJV)
27 Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid.

Daniel 8:25 (KJV)
25 And through his policy also he shall cause craft to prosper in his hand; and he shall magnify himself in his heart, and by peace shall destroy many: he shall also stand up against the Prince of princes; but he shall be broken without hand.

Luke 21:36 (KJV)
36 Watch ye therefore, and pray always, that ye may be accounted worthy to escape all these things that shall come to pass, and to stand before the Son of man.
