Redemption is a word that means "a purchase" or "a ransom. Every person is a slave to sin; only through the price Jesus paid on the cross is a sinful person redeemed from sin and death.It has been made clear that every person stands in need of redemption. Why? Because every person has sinned and come short of God’s Glory. Romans 3:23 AMP:  23 since all have sinned and continually fall short of the glory of God, 24 and are being justified [declared free of the guilt of sin, made acceptable to God, and granted eternal life] as a gift by His [precious, undeserved] grace, through the redemption [the payment for our sin] which is [provided] in Christ Jesus, 25 whom God displayed publicly [before the eyes of the world] as a [life-giving] sacrifice of atonement and reconciliation (propitiation) by His blood [to be received] through faith.
