The Lord Almighty has sworn, “Surely, as I have planned, so it will be, and as I have purposed, so it will happen. I will crush the Assyrian in my land; on my mountains I will trample him down. His yoke will be taken from my people, and his burden removed from their shoulders.” This is the plan determined for the whole world; this is the hand stretched out over all nations. For the Lord Almighty has purposed, and who can thwart him? His hand is stretched out, and who can turn it back?
This song begins with a picture of the second coming of Jesus Christ, when “every knee shall bow in heaven and on earth and under the earth” (Philippians 2:10). All of our chains will be broken and the children of God will finally be full and free. Verse 2 of the song shows the need for us to let God into our hearts because he is “here to set the captives free.” For who can stop the Lord Almighty?
When God proposes a plan of action, it will be so. Though this passage speaks of the oppression of the Assyrians on God’s people it calls us to look at the greater oppression that He has redeemed His children from, hell. “On my mountain I will trample him down (Isaiah 14:25).” God has promised to trample the enemy on the mountain and remove the burdens from the shoulders of His people. When God makes a promise, he never backs down from it. God gave us His son, Jesus, to trample the enemy on the mountain of the Lord, on the cross where He was crucified.
In Revelation 5, John writes about a Lion of Judah who has conquered. He also writes about a Lamb standing among the elders as though it had been slain. These are both images used to depict Jesus; He is both the conquering Lion and the Lamb who was slain. He is both the fulfillment of the Old Testament prophecy and the perfect and ultimate sacrifice for our sins. There is nothing that can stop the Lord from fulfilling his purposes (Isaiah 14:24).
