1. "You are my servant" (1-9)
The nations and their idols seem strong and influential, while Israel seems weak, having been taken captive into Babylon. But God is sovereign over all nations. He would call Cyrus the Persian to service to destroy and liberate his people (2-4). Idols were no help to their nations as conquering kingdoms came and went. But Israel is different. They were hand picked by God, and should know and keep this identity.
2. "I myself will help you" (10-29)
In contrast to the impotence of idols, God was with his people to hear and to act. Their situation after exile was difficult, unsure of who to trust or where to get help. The Lord says three times: "I will help you (10, 13, 14)." The Lord is our Redeemer. He satisfies the thirsty in a desert. He knows the end from the beginning, while idols know nothing. Let's come to him, consider his power and trust in his help.
