King James Bible
"To redeem them that were under the law, that we might receive the adoption of sons."
Paul describes Christ's mission to purchase freedom for those enslaved to the Mosaic law's demands and its curse. The redemption metaphor draws from slave markets where a price was paid to liberate captives, emphasizing that Christ's incarnation had a specific liberating purpose for those bound by legal requirements they could not fulfill. The goal of redemption transforms believers from slaves to fully adopted children with inheritance rights. In Roman adoption practices, adopted sons received the same legal status as biological children, illustrating how believers gain intimate family relationship with God and all its privileges through Christ's work.
