“Instead of Christ” comes first and uses wisdom and beauty to convince you that he is Jesus. Luke 17:34 KJV tells you about two in bed when he arrives:
I tell you, in that night there shall be two men in one bed; the one shall be taken, and the other shall be left.
Not being awake may handicap you as Mark 13:37 KJV warns you to “Watch”. Neither Mark nor Luke wants you to be the first one taken.
And what I say unto you I say unto all, Watch.
Besides sleeping when he arrives, “Instead of Christ” looks for you to be working for him. Anticipating “Rapture” is working for him; it makes it easy to harvest Christians. Matthew 24:40-41 KJV shows this harvest in process:
Then shall two be in the field; the one shall be taken, and the other left.  Two women shall be grinding at the mill; the one shall be taken, and the other left.
Recognizing that “Taken First” is “Raptured” by “Instead of Christ” bolts you into action.
Researching your King James Bible for the word “Rapture” teaches you that it is not there and a review of the manuscripts tells why. A word not in the manuscripts cannot be translated and the word “Rapture” is not there either. You finally come to the realization that “Rapture” is simply a word, a tool used by man to blind you to the fact that two Christ are coming. Matthew 24:23-26 KJV shows you conditions as the “Instead of Christ” is arriving:
Then if any man shall say unto you, Lo, here is Christ, or there; believe it not.  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.  Behold, I have told you before.  Wherefore if they shall say unto you, Behold, he is in the desert; go not forth: behold, he is in the secret chambers; believe it not
“You “Believe it not” because Jesus Christ comes second. Rev. 12:9 KJV shows “Satan’s Coming”; it shows “Instead of Christ deceiving the whole World:
And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
God is sending both Christs! Luke 21:21-22 KJV talks about the days of vengeance that accompany the “Instead of Christ”; it also discusses coping with him:
