Why is it important to know Christ's role as our Substitute?

The role of Christ as our Substitute is foundational in Reformed theology. This doctrine highlights how Christ took upon Himself the sins of His people, bearing the weight of their guilt in His atoning death. In Psalm 22, which was referenced, we find the depiction of Christ as the one who suffered in our place. This not only fulfills the requirements of divine justice but also provides believers with assurance of salvation and the blessings of the covenant of grace. Acknowledging Him as our Substitute allows us to rest in the finished work of Christ and celebrate our eternal security in Him.
