What causes the remnant of Israel to recognize Jesus and be saved and grafted in?
When the remnant of Israel sees 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. Their unbelief will be removed, and the nation will be saved in a moment and grafted in.
Les explains that the remnant of Israel will be protected by God for 3.5 years of the horrors of tribulation, just as He kept Israel 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. Their unbelief will be removed, and they will be grafted in again—a nation born in a day, saved in a moment.
And they also, if they abide not still in unbelief, shall be graffed in: for God is able to graff them in again.
