How do we know that Christ died for His people?

The assurance that Christ died for His people is drawn from numerous scriptural affirmations, especially verses that describe His role as the appointed substitute. Jesus' work on behalf of the elect is showcased through His perfect life, sacrificial death, and resurrection, which affirms that justice was satisfied for those given to Him in the covenant of grace. Romans 4 further clarifies that His righteousness is imputed to those who believe, reinforcing the doctrine of imputation and saving grace.
