Redemption is God's act of reclaiming and delivering sinners through Jesus Christ, establishing them as His own through the cost of His Son's blood.
Believers are redeemed not merely from something, but unto Someone. Having been bought with a price, they no longer belong to themselves, but to the One who redeemed them.
See in Scripture: Mark 10:45; Romans 3:24; Ephesians 1:7; 1 Peter 1:18–19
