God is a faithful God. Faithfulness to do as He has promised is one of His divine attributes. Long ago, God made unconditional promises to Abraham involving his physical descendants (Gen. 12:7, 15:18, 17:7-8). In the future millennial dispensation, Israel will be restored in the Promised land and exalted as the greatest nation on the earth (Ez. 36:22-38, Jer. 31:1-14, 27, 31-40, 33:6-26). The Gentile nations will serve Israel and be blessed through them (Isa. 60:11-14, 61:3-9, 62:1-5). There is no word which God has spoken that will return to Him null and void (Isa. 55:11).
