Why is the resurrection of Christ crucial for Christians?

The resurrection of Christ is the cornerstone of the Christian faith. As stated in Romans 4:25, Jesus was delivered for our offenses and raised again for our justification. This means that through His resurrection, believers are assured of their justification before God; their sins are forgiven, and righteousness is imputed to them. Moreover, His resurrection empowers believers, as seen in Romans 5:10, where being reconciled through His death means that we shall be saved by His life, providing a living hope and assurance of eternal life.
