Bishop Sheen argues that the resurrection of Jesus Christ is the most important of all miracles and provides strong evidence for his divinity. He points out that the resurrection was not expected by the apostles and that they were convinced of its reality despite their initial skepticism. Bishop Sheen also addresses two popular theories that attempt to explain away the resurrection, the lie theory and the psychological theory, and demonstrates why both are inadequate. He concludes by emphasizing the significance of the resurrection as a call to die to what is holding us back and to embrace the risen Christ.
