When will the seven-year tribulation begin?
The seven-year tribulation begins when the Antichrist signs a seven-year treaty with the nation of Israel. At that signing, the curtain rises on prophecy, and God resumes prophetic dealings with Israel. Until then, no prophecy is being fulfilled; the stage is merely being set.
Les teaches that all prophecy is directed to the nation of Israel. Because God is not yet dealing with the nation, prophecy itself is not being fulfilled today; the stage is being set, the props are being put in place, and the players are getting ready. The curtain will rise at the signing of the seven-year treaty by the Antichrist and the nation of Israel, and then the seven-year period of tribulation begins, which is God dealing prophetically with Israel. The fulfillment of prophecy remains yet future.
