How do we know that Christ's atonement was sufficient for our sins?

The assurance of Christ's sufficient atonement lies in His resurrection, which serves as the validation of His victory over sin and death. Romans 4:25 states, 'He was delivered for our offenses and raised again for our justification.' This means that those whom Christ died for are justified—declared not guilty—before God. The resurrection is not merely a fact of history but a powerful declaration that Jesus is indeed the Son of God, who has effectively redeemed His chosen people. Without the resurrection, the sacrifices of Christ would be rendered ineffective, and our hope would be in vain.
