"If Jesus did not rise from the dead, then Christianity would be a false religion, we would have no hope, our loved ones would be gone for good, and we would still be in our sins. I appreciate Philip Schaff’s summary on the importance of the Resurrection based on Paul’s words:
"The Christian church rests on the resurrection of its Founder. Without this fact the church could never have been born, or if born, it would soon have died a natural death. The miracle of the resurrection and the existence of Christianity are so closely connected that they must stand or fall together. If Christ was raised from the dead, then all his other miracles are sure, and our faith is impregnable; if he was not raised, he died in vain and our faith is vain. It was only his resurrection that made his death available for our atonement, justification and salvation; without the resurrection, his death would be the grave of our hopes; we should be still unredeemed and under the power of our sins. A gospel of a dead Saviour would be a contradiction and wretched delusion. This is the reasoning of St. Paul, and its force is irresistible.
"The resurrection of Christ is therefore emphatically a test question upon which depends the truth or falsehood of the Christian religion. It is either the greatest miracle or the greatest delusion which history records." . . .
