The Mystery of the Blindness of Israel is that the Gentiles are now being reconciled to God because of her unbelief. However, this blindness will only last until the fulness of the Gentiles comes in, at which time Israel will see the Messiah, Jesus, for Who He truly is and will be saved. Therefore, do not be ignorant of this mystery or high minded against Israel, for she belongs to God and He will save her.
