How do we know Christ's sacrifice is sufficient for salvation?

The sufficiency of Christ's sacrifice for salvation is deeply rooted in the doctrine of imputation. As articulated in the sermon, our sins were imputed to Christ, and in exchange, His perfect righteousness is imputed to us (2 Corinthians 5:21). This divine exchange underscores the completeness of His sacrifice. The requirement for justification before God is fulfilled through Christ’s life, death, and resurrection, evidenced by Romans 4:25, where it states that He was delivered for our offenses and raised for our justification. Thus, believers can confidently rest in the assurance that through faith in Christ, they are fully redeemed and forgiven.
