Only a christian can turn into a whore,as the rest of the world already are...Christians will fall for satan thinking He's Christ ,turning them from being a virgin
II Corinthians 11:2 "For I am jealous over you with godly jealousy: for I have espoused you to one husband, that I may present you as a chaste virgin to Christ."
For a young woman to be "espoused" to her husband means that she is completely committed to him, even before the vows have been exchanged. Paul is using this relationship whereby we could understand the emotions of Christ towards His bride. The feeling and commitment goes both ways, and applies to the man as much as it applies to the woman. It is no great secret what causes virginity to be lost, for it is being unfaithful sexually to the one you are espoused to marry.
If a woman has been unfaithful, and is with child, how could she expect that she could be accepted by the man she was espoused to, when she is carrying another man's child? Paul is afraid that if Christians start listening to these fairy-tale preachers, they will be taken by the wrong christ, or Satan the Antichrist [the instead of Christ]. Then when Jesus Christ returns at the seventh trumpet, they will be found unworthy to be part of "the bride of Christ". Remember what Jesus said in Matthew 24:19; "And woe unto them that are with child, and to them that give suck in those days!" He was not referring to a mother with a child in her womb, but spiritually speaking, Christians that have given themselves over to the wrong husband. In ignorance they will have been deceived into climbing into the spiritual bed of Satan, and their hearts have been given over to the Satan.
If you are one of the whores of Satan, than you cannot be one of the virgins of Christ waiting with your lamps full of oil [which is the truth from God's Word] that is waiting for the coming of the bridegroom, which is Jesus Christ. Paul now is putting it into a language that most anyone can understand. Paul is saying; "I'm afraid that one of these false teachers is going to seduce you."
