Why is everything falling into place like it was at Christ's first advent?
Because the Church will be removed at the Rapture, allowing the prophetic program to resume. Israel is back in the land as at Christ's first coming, will soon have a Temple and return to Judaism and Law, and the revived Roman Empire and European community is nearly complete, setting the end-time stage for Christ's second coming to Israel.
Les explains that once the Church is complete and taken out of the way in the Rapture, the prophetic program will continue and be completed. He illustrates this by sliding the two bumps together: as soon as the Church is out of the way, the prophetic program goes right on. Looking at the situation, Israel is back in the land like she was at the time of Christ's first coming. They will soon have their Temple and go back under Judaism, the Law, and Temple worship. The revived Roman Empire is already on the scene, and the European community is just about jot and tittle complete. Thus everything is falling into place to be just like it was at the time of Christ's first advent. Though technology has exploded, it all serves the sole purpose of bringing about the end-time scenario for Christ's second coming to the nation of Israel.
