What makes the remnant of Israel finally recognize Jesus as the Messiah?
When the remnant of Israel sees Him coming in the clouds of glory with power, crushing the Gentile world that has taken over the Middle East, they recognize who He is. Their unbelief is removed, and the nation is saved in a moment and grafted back in.
Les teaches that their unbelief will one day be removed, and they will be grafted back in again. He asks, "Will a nation be born in a day?" and answers, "Absolutely!" The remnant will be the ones in the mountains described in Matthew 24, protected for 3.5 years of the horrors of tribulation, kept as Israel was kept in the wilderness under Moses. When they see Him coming in the clouds of glory, in power, crushing the Gentile world that has taken over the Middle East, they will recognize who He is. They will see Him, and the remnant nation will be saved in a moment and grafted in again.
