A fear not of God
Fear Not, I Have Redeemed Thee
God's people are heading into exile, or already tasting it, and it feels like waters closing over their heads and fire at their backs. They have sinned, they have been scattered, and they might well believe God is finished with them. Into that despair the Creator speaks, and He does not lead with judgment. He leads by naming them as His own.
“But now thus saith the LORD that created thee, O Jacob, and he that formed thee, O Israel, Fear not: for I have redeemed thee, I have called thee by thy name; thou art mine.”Isaiah 43:1
The moment
This word comes after chapters of hard truth about Israel's failure, so the fear here is not only of Babylon but of abandonment, the dread that they have finally used up God's patience and belong to no one now. The images that follow, passing through waters and walking through fire, are the very things that drown and consume, the exact shape of their worst fears about exile. What makes the fear real is that the danger is in part deserved; they are not innocent victims. And yet God interrupts the fear at its root, not by promising there will be no waters at all but by declaring whose they are as they pass through them.
Why we need not fear
God gives three reasons the fear can rest. I have redeemed thee: a price has been paid, the claim of judgment answered, so they are bought back rather than cast off. I have called thee by thy name: they are not a faceless crowd but known personally, singular, remembered. Thou art mine: the relationship holds even in exile. Fear can be set down because redemption is past tense, already accomplished, and being owned by God is not something the waters can wash away. They will pass through, but they will pass through as His.
How Christ answers this fear
The redemption Isaiah announces was still a promise waiting for its price; at the cross the price is finally named and paid. Christ is the redeemer who buys His people back not with silver but with His own blood, so that thou art mine becomes a covenant sealed in a way nothing can break. He Himself went through the deepest waters, down into death, and through the fire of judgment, so that when His people pass through their own floods they are never passing alone. To belong to Christ is to be called by name by the Shepherd who lays down His life, and no one is able to pluck them out of His hand.
Questions people ask
What does Isaiah 43:1 mean?
Speaking to an Israel facing exile and fearing abandonment, God says fear not because He created them, redeemed them, called them by name, and claims them as His own. The verse grounds comfort not in the absence of trouble but in belonging: they will pass through deep waters, but as people who have been bought back and are personally known by God.
Why does God say fear not, I have redeemed thee?
Redemption means a price was paid to buy someone back. Israel feared that their sin had ended their relationship with God. By pointing to redemption, God says the decisive act is already done; they are His by purchase and by name. The fear of being cast off can rest because being owned by God cannot be undone by any flood.
