If they disbelieve that He has risen because He is not seen, then those who refuse belief must also deny the natural order. For it is proper to God to be invisible and yet to be known from His works, as was said above.
If the works are absent, they are right to disbelieve what does not appear. But if the works cry aloud and demonstrate it clearly, why do they willingly deny the life of the Resurrection that is so plainly manifested? Even if their understanding has been impaired, they can still perceive with their outward senses the undeniable power and divinity of Christ.
Even if a blind person cannot see the sun, he knows that the sun is above the earth by perceiving the warmth that comes from it. In the same way, even if our opponents do not yet believe and remain blind to the truth, they should at least recognize His power in those who do believe, and they should not deny Christ’s divinity or the Resurrection accomplished by Him.
Obviously, if Christ were dead, He could not drive out demons or despoil idols, for demons would not obey one who was dead. But if they are visibly driven out when He is named, it is clear that He is not dead—especially because demons, who see things unseen by human beings, would know if Christ were dead and would not obey Him at all.
But what ungodly people refuse to believe, the demons see: that He is God. For this reason they flee from Him and fall at His feet, saying what they also said when He was in the body: "We know who You are, the Holy One of God," and, "Ah! What have You to do with us, Son of God? I beg You, do not torment me."
Since the demons confess Him and His works bear witness day by day, it should be clear—and let no one act shamelessly against the truth—that the Savior raised His own body and is the true Son of God. He is from God as from His Father, His own Word and Wisdom and Power. In later times He took a body for the salvation of all, taught the world about the Father, abolished death, and gave incorruption to all through the promise of the Resurrection. He raised His own body as the first-fruits of that Resurrection and, by the sign of the Cross, displayed it as a trophy over death and its corruption.
