were produced. Had water the power of giving birth to eyes, or clay of creating light? Certainly not, especially as water could be of no use to a blind man, and clay would actually hinder the sight of those who could see. And how was it that a thing that itself in its own nature was injurious, became the means of restoring health; and that what was ordinarily hurtful to sound people, was then made the instrument of healing? You say that the power of God brought it about, and the remedy of God caused it, and that all these things of which we have been speaking were simply brought about by Divine Omnipotence; which is able to fashion new things from unwonted material, and to make serviceable things out of their opposites, and to change what belongs to the realm of things impossible and impracticable into possibilities and actual performances.
