How do we know redemption is true?

The doctrine of redemption asserts that Christ's sacrificial death on the cross was the ultimate fulfillment of God's plan to save His people from sin. Hebrews 9:12 tells us that Christ obtained redemption with His own blood, highlighting the sufficiency and finality of His sacrifice. This truth is crucial for believers as it assures them that their sins are forgiven and that they are reconciled to God. The concept of purchase by blood reflects the great cost of our salvation and magnifies the grace of God, as it was not earned but freely given through the sacrifice of Christ.
