How do we know Christ's blood is the means of our redemption?

The concept of redemption by Christ's blood is central to the Gospel. As stated in 1 Peter 1:18-19, we are not redeemed with corruptible things but with the precious blood of Christ, who is without blemish and spot. It is significant that Christ, being sinless and divine, is the only acceptable sacrifice to atone for human sin. Only through His blood can the curse of sin be removed, as He bore our sins in His body on the cross, fulfilling God's justice while providing grace to the sinner. This emphasizes the necessity of faith in Him alone for salvation.
