Isaiah 40:10 Meaning: Does God Come to Judge or Save?

The Hebrew word behind “strong” (or “mighty one”) is chazak. It describes firmness, someone you cannot push over. When the prophet says God comes as a mighty one, he means this is not just an act; it is who God is. The “arm” (zeroa) is a symbol of power throughout the Old Testament, the arm that brought Israel out of Egypt. Here it rules for him, meaning God does not need anyone else’s help. Then come two words side by side: “reward” (sakhar) and “recompense” (pe’ullah). The first means wages, like what a worker earns. The second means what is owed for work done. Together they say that God brings with him what each person deserves, not because we earn it, but because he is just. These words prevent us from imagining a God who is only gentle or only stern. He comes with both arms full.

Christian readers have seen this verse in different lights. Some, like Matthew Henry and Gill, apply it to the first coming of Christ, when God entered the world in weakness, yet with power to save and rule. Others, like Keil and Delitzsch, see both a first and a second coming: the same God who came as a shepherd will come again as a righteous judge. The Cambridge Bible notes that the prophet’s mind is fixed on the return from exile, but his words expand to include the Messiah. What unites these readings is trust that God will come, and when he does, he brings both mercy and justice. No tradition reduces the verse to only one note.

Some people read “reward” and think the verse is about earning God’s favor by good deeds. In fact, the word sakhar here refers not to what we do for God, but to what God brings with him when he comes. It includes deliverance for his people and justice against evil. The point is not that we deserve anything, but that God acts in perfect fairness. He does not come empty-handed.

This week, you may feel like your situation is too big for you. Maybe you face a conflict at work, a health worry, or a family tension that never seems to end. This verse asks you to stop and look: the Lord is coming as a mighty one. His arm rules for him, which means you do not have to make everything right by yourself. He has reward and recompense with him. You can let go of the need to balance the scales on your own. Instead, you can trust the One who comes with both power and justice. Tomorrow morning, before you check your phone, picture that arm ruling, not over you, but for you.
