How do we know that the substitutionary death of Christ is true?

The doctrine of Christ's substitutionary death is firmly rooted in the teachings of scripture, specifically emphasized in passages such as Romans 3:25. This doctrine teaches that Jesus died in the place of sinners, taking upon Himself the penalty for sin that would lead to their condemnation. His perfect life and sacrificial death fully meet the requirements of God's justice, thus providing a means for sinners to escape wrath and receive grace. Without this foundational truth, the concept of God's grace would be meaningless, as there would be no way for God's anger against sin to be appeased. The perfect obedience and the shed blood of Christ represent the fulfillment of all sacrificial types found throughout the Old Testament, thereby certifying the truth of His redemptive work.
