When God says “Fear not: for I have redeemed thee, I have called thee by thy name; thou art mine” (Isaiah 43:1), He is speaking to a defeated people and reminding them that their whole existence, their forming and their rescuing, comes from Him alone; the words created and formed echo Genesis, telling Israel that the same hands that made the world made them, and the word redeemed (from the family term for a kinsman who buys back his own) means God is not a distant judge but a near relative willing to pay to bring them home, so that when verses 2 and 3 promise His presence through waters, rivers, and fire, the point is not that hardship disappears but that God walks through it alongside them, holding them as those who are named, known, and owned by Him.
