Therefore shall the strong people glorify thee, the city of the terrible nations shall fear thee.

Isaiah 25:3

Explanation:
Because of God’s wonders (v1), plans (v1), and power against the evils of the city (v2), there will be two responses.
“Strong people” in this context are those who have been strengthened by God because they have believed on Him. These are the redeemed. Their response to God’s wonders, plans, and power is that of worship. They glorify God because of who He is and what He has done.
The response of “the city of terrible nations” who are now in a heap (v1) is that of terror. They now fear God because they understand the choice that they have made to go against the holy, righteous, and powerful Creator and Sustainer of the universe. There is fear, but at this point their fear is felt too late.

Application:
God deserves our worship while we deserve His wrath. This is why He sent His Son, Jesus Christ, to die for us. He wants us to choose Him. We should glorify God for His wonders, plans, and power now.

Response:
Pick one of God’s wonders, plans, or an aspect of His power that you can worship Him for today.
