How do we know that redemption is secured by Christ's blood?

The doctrine of redemption is foundational to the Christian faith, and it is clearly articulated in the teaching that Jesus Christ's blood was offered up to God, fulfilling the requirements of divine justice. This truth is embodied in various Scripture passages, including Hebrews 9:12, which states that Christ entered the holy place with His own blood, having obtained eternal redemption for us. The idea of redemption denotes that a price has been paid in full, meaning that no further sacrifice is needed, and therefore those for whom Christ died are fully justified.

This is significant because it asserts that redemption is not merely a possibility for everyone but a definite reality for the elect. As stated in Romans 5:9, we are justified by His blood, demonstrating that the debt of sin has been fully satisfied. The truth that Jesus paid the debt for His people ensures that their salvation is secure and highlights the assurance found in Christ’s substitutionary work on the cross.
