What will happen when the age of grace ends?
God will stop the age of grace, cast aside the Gentiles who rejected His salvation, and set them into the horrors of the tribulation. At that same time, He will turn again to His covenant people, Israel, and graft the natural branches back into their own olive tree.
Les teaches that God is not through with Israel, even though the nation has been set aside for over 1900 years; in God's program that is only a flick of the eyelid. Gentiles were brought in by grace and made partakers of the fatness of the Abrahamic promises, but they are warned that if they reject it as Israel did, they will be cut off. The day is coming when God will stop the age of grace, set the Gentiles into the horrors of the tribulation, and turn again to His covenant people. Israel, the natural branches, will be grafted back into their own olive tree, while the Gentiles who rejected will be cast aside.
