How do we know Christ's suffering was necessary for our salvation?

The suffering of Christ was necessary as it fulfilled the prophetic Scriptures that indicated a Messiah who would bear the sins of His people. In Isaiah 53:5, it states that 'He was wounded for our transgressions, He was bruised for our iniquities.' This shows that His physical and emotional pain was directly linked to our salvation. By experiencing such depths of suffering, He became the perfect sacrifice, justifying many before God, as it was through His pain that peace was established between humanity and the Father. Without this atonement, there would be no reconciliation for our sinful state.
