How do we know Christ's substitutionary death is true?

The truth of Christ's substitutionary death is deeply rooted in the scriptures. Romans 5:6-10 discusses how Christ died for the ungodly, offering a propitiation for our sins. Additionally, Old Testament prophecies, such as Isaiah 53, forecasted a suffering servant who would bear the iniquities of many. The historical account of the crucifixion corroborates this, as it detailed the circumstances of his death. The theological implications of this act - that through his blood we are justified and reconciled to God - confirm its truth within the fullness of God's redemptive plan.
