What is the Kinsman-Redeemer in the Bible?

The concept of the Kinsman-Redeemer is deeply rooted in the Old Testament, primarily illustrated in the book of Ruth. The Kinsman-Redeemer was a relative who had the obligation to redeem family members in need, which includes buying back land or marrying a widow to preserve family lineage. This role symbolizes Christ, who, as our Kinsman-Redeemer, fulfills all the requirements necessary for our redemption. He took on human flesh and became like us, offering Himself as the perfect sacrifice for our sins, thus securing our redemption and ensuring our spiritual inheritance.
