The New Testament emphasizes that we are spiritual debtors. The only acceptable price for the debt of our sin is the precious blood of Jesus. When that price was paid, the debt was canceled and sinners were set free. What is remarkable is that the incarnate Jesus is not ashamed to call us brothers and sisters (Heb. 2:11). He really is our kinsman redeemer.
Pawn shops, foreclosures, and bankruptcy highlight the reality of financial crisis that people experience in our day. Have you ever needed financial assistance? Maybe you have asked a family member to help pay your credit-card bill, student loan, or mortgage payment. Or maybe a family member has asked you to help pay off a debt.
The need for financial help is a useful way to introduce the idea of the kinsman redeemer. In short, a kinsman redeemer is a relative who, at his own expense, pays off the debts of another. But this theme points beyond finances, because our greatest need is not for someone to pay off financial debts—however great that need might be—but for someone to redeem us from the debt our sins have incurred. This is how the Old Testament idea of the kinsman redeemer bears on our understanding of redemption through the sacrifice of Jesus Christ.
The idea of a kinsman redeemer is laid out in the Levitical laws, displayed by men such as Boaz and Jeremiah, and fulfilled by Jesus, who paid for our sins with His precious blood.
Instructions for a kinsman redeemer are given in Leviticus 25, in close connection to the Year of Jubilee, when debts are forgiven, family land is returned, and prisoners are set free. If an Israelite went into debt, he might have to sell his inherited land or perhaps even sell himself into slavery. If this were to happen, a close relative would pay the price to redeem the land and/or buy him out of slavery (the closer the family relation, the greater the obligation to act as a kinsman redeemer). The cost of redemption was calculated proportionately to the Year of Jubilee.
