It's clear that LaHaye has not done his homework, even homework as basic as counting Roman emperors. It makes me wonder what else he has failed to double-check. It also makes me wonder why I should consider his research reliable. Actually, it gets even worse. He could have gotten this information out of any Bible dictionary or encyclopedia.
Contradictions run all through the book.
When the church is removed at the Rapture, so is the Holy Spirit. Yet, that same Holy Spirit apparently indwells Tribulation believers in exactly the same way that He was indwelling the church. If we want to be consistent, then we would have to say that the Holy Spirit's restraining influence is taken out of the way only until the first Tribulation convert comes to Christ. When that happens, the Holy Spirit is back, and presumably in a position to do His restraining work again. So the Holy Spirit is alive and well and doing pretty much the same thing He was doing in the church, except that now it's the same thing, only different.
