That's true, and the American people are ready to be deceived and will be even more so as this nation goes further into the abyss.
It is important, though, for people to know the traits of the Antichrist - especially those who will be here after the church is taken.
It is vital that people have that information so even if they reject the doctrine of the Rapture, and the Tribulation, and everything else prophesied by God, they will know the Antichrist for what he is when he comes to power and will take advantage of their one last opportunity to accept Christ's offer of salvation.
Maybe, Though I do question if they will be able to discern who the Anti-Christ is, after the believers are taken , as the great deception God said he would likely be in full swing so that they, those who have already been presented with Christ but rejected Him, will indeed believe that lie.
Those who have been presented with the Gospel of Christ prior to the church being taken will NOT have another opportuntity for salvation during the tribulation..... People who will be saved out of the tribulation are only those who have never heard the Gospel before. The Jewish Christians left to witness to these people will surely be equipped for that task and will undoubtedly know how and in what manner to make the anti-Christ known for who he really is.
