Why is Jesus called our kinsman redeemer?

The term 'kinsman redeemer' originates from the Levirate marriage laws found in Deuteronomy 25, where a close relative had the obligation to redeem family members in need. Boaz served as a kinsman redeemer for Ruth, but this perspective aptly points to Christ, who became our kinsman through His incarnation. As expressed in Ephesians 5:25-27, He loved the Church and sacrificed Himself to redeem her. This union is profound, as it establishes a vital connection between Christ and His people, affirming the Reformed understanding of salvation anchored in Christ's finished work on the cross.
