Isaiah 25 is a song of praise to God for His faithfulness, power, and the promises He will fulfill. Go here for chapter notes. The chapter can be broken down into the following key themes:Praise for God's Faithfulness and Power (verses 1-5): Isaiah praises the Lord for His wonderful deeds, plans formed of old, and for making a city into a heap of ruins. The prophet speaks about how God has been a stronghold to the poor and needy and a shelter from the storm.Banquet on Mount Zion (verses 6-8): Isaiah prophesies about a future time when the Lord will prepare a feast of rich foods and aged wine on Mount Zion for all people. He will swallow up death forever and wipe away tears from all faces. This represents the ultimate victory of God over death and sorrow.Rejoicing in Salvation (verses 9-12): The people of God will rejoice in His salvation. They will proclaim, "Behold, this is our God; we have waited for him." The Lord will bring down the pride of the ruthless and lay low the lofty city.
