What does it mean to be redeemed by the blood of Christ?

Redemption by the blood of Christ is a foundational doctrine in Christianity, implying that Jesus paid the ultimate price for sin by offering Himself as a sacrifice. According to Scripture, believers are said to be redeemed not by corruptible things but by the precious blood of Christ (1 Peter 1:18-19). This redemption restores the relationship between the sinner and God, cleanses from the guilt of sin, and secures eternal life. The blood signifies the atonement made for believers, enabling them to approach God with confidence and assurance of salvation.
