Anyone seeking proofs that God has been manifested to us in flesh should look to the works. For no one would have another proof even that God exists at all except the testimony given through the works themselves. Thus, just as by looking to the whole and observing the ordering of the world and the benefits from God that are active in our life we perceive a power above these things that produces what comes to be and preserves what exists, so also, in the case of God manifested to us through flesh, we take the miracles shown in His works as sufficient proof of the manifestation of divinity, recognizing in all the deeds that have been recorded those things through which the divine nature is characterized.
It belongs to God to give life to human beings; to God to preserve existing things through providence; to God to grant food and drink to those whose life is in the flesh; to God to benefit the one in need; to God to bring nature, when it has been diverted by weakness, back to itself through health; to God to exercise oversight alike over all creation—earth, sea, air, and the regions above the air; to God to possess power sufficient for all things; and, above all, to be stronger than death and corruption. If, then, the account concerning Him lacked any of these things and things like them, those outside the faith would reasonably reject our mystery. But if everything by which God is understood is seen in the narratives concerning Him, what prevents faith?
