God’s nature (v. 29). “I am the Lord, I change not” (Mal. 3:6). “God is not a man that he should lie; neither the son of man, that he should repent” (Num. 23:19). God’s gifts to Israel, and God’s calling of Israel, cannot be taken back or changed, or God would cease to be true to His own perfect nature. The fact that Israel may not enjoy her gifts, or live up to her privileges as an elect nation, does not affect this fact one bit. God will be consistent with Himself and true to His Word no matter what people may do. “Shall their unbelief make the faithfulness of God without effect?” (Rom. 3:3, literal translation).
