What does it mean for Christ to be our substitute?

The concept of Christ as our substitute is foundational in Reformed theology. It signifies that Christ willingly took upon Himself the sins of His people and bore the punishment that we rightly deserved. This is illustrated in Isaiah 53:5, which notes that He was wounded for our transgressions, highlighting His role in the atonement as the one who suffers in place of sinners. By assuming our guilt and suffering the wrath of God, He satisfies divine justice, allowing for our reconciliation with God. This substitutionary atonement is not just a transactional action; it is also a profound demonstration of God's love for His elect, assuring them of their complete forgiveness and the assurance of eternal life through faith in Christ.
