Will God ever restore Israel to their land and fulfill His promises to them?
Yes. Scripture says God promised from the beginning that He would not give up on Israel. Though they were dispersed and suffered judgment, He will one day bring them back to the land and fulfill all the promises He made to their forefathers.
Les teaches that because Israel rejected their Messiah, they lost their temple, they lost their land, and they were driven into dispersion; they have been in the ghettos and through the Holocaust. Yet God also promised from day one that He would not give up on them. One day He will yet bring them back, bring them to the land, and fulfill all the promises He made to their forefathers. In Romans chapter 11, Paul has a heart for Israel and defends the nation, showing they are not going to be completely annihilated.
