1. Cyrus, God's instrument (1-13)
The Lord holds all nations in his hand. He would raise Cyrus as ruler over all the world, for the sake of his people Israel. All people will know there is none besides the LORD, who for the sake of his children has rebuilt the city of Jerusalem and the temple to his name. The LORD is sovereign over the nations, and also each human being, as he created each one. He has a plan and purpose for each of us, to reveal his holiness and glory in the world.
2. "Turn to me and be saved" (14-25)
Even Gentiles taken in captivity would acknowledge God is with his people. By rebuilding Israel, all nations would see the character and power of God, who saves his people with an everlasting salvation so they are never put to shame; who speaks truth, declaring what is right; and who is the righteous God. The testimony to all people through this is clear: "Turn to me and be saved, all you ends of the earth, for I am God and there is no other."
