How does Christ's blood redeem us?

In sovereign grace theology, Christ’s blood is central to our redemption because it fulfills God's demand for justice regarding sin. As noted in 1 Peter 1:19, redemption comes through the 'precious blood of Christ.' This means that His sacrificial death on the cross was necessary to atone for the sins of His people, serving as the perfect and sufficient sacrifice that God accepted. Since Christ was sinless, His blood has the power to cleanse us from all unrighteousness, ensuring that no traditional or personal merit can compete with this divine provision for our salvation.
