How do we know that Christ's sacrifice redeems us?

We know that Christ's sacrifice redeems us through the clear teaching of Scripture that illustrates how His blood serves as payment for our sins. Passover serves as an important type of this redemption, where the Israelites were saved through the blood of the lamb. In 1 Peter 1:18-19, we learn that we are redeemed not with perishable things, but with the precious blood of Christ. Moreover, Romans 5:9 assures us that we are justified by His blood and saved from the wrath of God. Thus, the efficacy of Christ’s redemptive work is rooted in His sacrificial death, which satisfies divine justice and restores our relationship with God, demonstrating God's sovereign grace in action.
