How do we know that Christ's blood is precious?

The preciousness of Christ’s blood is affirmed in 1 Peter 1:18-19, where it emphasizes that believers were redeemed not with corruptible things, but with the precious blood of Christ. His blood is precious because it represents the highest value invested in our redemption—God's own Son willingly gave His life for us. As Jesus described in John 10:18, He laid down His life voluntarily, and in doing so, He fulfilled divine justice and reconciled believers to God. The efficacy of His blood to cleanse us from sin further solidifies its importance, demonstrating how it stands apart from any temporal or earthly riches, establishing our standing before a holy God through a perfect sacrifice.
