What does Isaiah 26:14 mean?
This passage boldly states that the Lord will eventually establish peace for Israel and Judah. He has been the true source of every victory throughout their long history (Isaiah 26:12; Psalm 44:1–3).The prophet has admitted that other lords have ruled over his people in the past. These may have been the kings of invading armies or the false gods of other nations. Isaiah has made clear that those "other lords" are no longer honored or even remembered (Isaiah 26:13). Now he adds that they are all dead. They are "shades," ghosts of memory, who will never walk the earth again. Even the memory of them is wiped out, God's destruction is complete. Only the Lord, Israel's true ruler, remains.
The same can be said of those who come to God through faith in Christ as Lord and Savior. Whatever former "lords" or passions ruled their lives, the Lord has set them free and become their one and only true king (Galatians 4:8).
Isaiah 26:1–15 celebrates the Lord's future victory over wickedness on the earth and looks forward to the coming of God's judgment. Isaiah longs for that judgment to come. But the prophet knows the Lord gives perfect peace to all who stay focused on trusting Him. Only the Lord God remains of all those who attempted to rule over Israel.
Chapter 26 is a song to be sung in the land of Judah during the time of the Lord's reign as king over the earth. The towering city of wickedness has been replaced by the strong city of salvation. Isaiah waits, longing for the Lord to come and judge the sinfulness of the world. The Lord will bring peace to Israel for good. Their other rulers are dead and not worthy of remembering. The Lord's discipline has caused His people to turn back to Him. The dead among them will be resurrected after the fury of His judgment.
