Matthew 28:1-15 shows us that everyone agrees that the tomb was empty on the first day of the week. Where they disagree is on the question: Why was the tomb empty? In this sermon several of the most persuasive evidences and arguments for the resurrection are mentioned, but the sermon means to confront people with the authority of the risen and reigning Lord. And the sermon takes seriously that unbelievers will interpret these things through sin-stained glasses but believers have been changed by the work of the Spirit so that they will interpret these things wanting to believe the truth as we find it in the Scriptures.
The Heidelberg Catechism Q&A 45 says this,
“What benefit do we receive from the resurrection of Christ? First, by his resurrection he has overcome death that he might make us share in the righteousness which he has obtained for us through his death. Second, we too are now raised by his power to a new life. Third, the resurrection of Christ is a sure pledge to us of our blessed resurrection.”
