How do we know that Christ is our surety and substitute?

The doctrine of Christ as our surety and substitute is foundational to understanding the gospel. Jesus, being God manifest in the flesh, bore the sins of His people and drank the full cup of God’s wrath at Calvary. His fulfillment of the law and perfect obedience allow for His righteousness to be imputed to believers. The concept of imputation, beautifully articulated in Romans, shows how our sins were charged to Him, while His righteousness is credited to us. This mutual exchange is not just theological jargon but the very essence of salvation, ensuring that believers are seen as righteous before God.
