The Bible predicts a future time when Israel will be regathered in belief and will then enter into the kingdom for a thousand years. The same Scriptures also tell us of a time when Israel will be regathered in unbelief, before the tribulation in order that God may complete His plan for national Israel.
The current nation of Israel is the beginning of fulfillment of just such prophecy. Modern Israel is the result of God’s direct intervention in history.
