Isaiah 26:15

Increased the nation. That is, Judah. In contrast, Judah’s enemies had all perished (v. 14). The scene of victory here depicted will be fully realized only when Christ makes all His enemies His footstool (Ps. 110:1; Matt. 22:44), and when “the kingdoms of this world” are subjected to His wise and just rule (see Dan. 2:44; Rev. 11:15). God will accomplish in the world made new what He would have wrought for Israel had that nation been faithful to Him (see pp. 27-30). Removed it far. According to God’s original plan, the borders of Israel would gradually have been extended until they embraced the whole world (see pp. 28-30). When Israel rejected Christ and was, in him, rejected, the Christian church inherited the promise of worldwide expansion, to be finally and completely realized in the new earth (see pp. 30, 35).
