I do have a couple of thoughts on the identity of the Anti-Christ. (None based upon this book.) First, the hypothesis that he will be Roman seems to be based upon scripture that indicates he will be from the sea of Gentiles. Well, that's a big sea. One wonders if the Anti-Christ could be Arab. Of course, we tend to speculate on such things based upon recent world events. That said, I think we should remember that the Anti-Christ will not necessarily be easily identified. After all, he is a deceiver and one wonders if he would appear carrying a sign proclaiming himself as the Anti-Christ. Perhaps one argument in favor of the Rapture before the emergence of the Anti-Christ is that the absence of the Church would make this deception much easier.
He would be more easily identified if you would read some of the many hundreds of posts posted in the last 3-1/2 years on the subject by Thinkin' Gal.
