"Men mistake the mystery of the perfection of providence for the impossibilities of a contradiction if they insist on limiting God's mind by the measure of their own. We must take things as they are, use them, minister to them; for our constructive capacity does not go beyond the world of the artificial--houses, barns, clocks, cloaks. We do not make trees or cats or sunrises. Because these things are beyond our planning, we absurdly conclude that they are beyond all planning, that they need no mind behind their orderly existence. These things do not need men, so they do not need God; they are necessary, with no word of explanation of that necessity."
St. Thomas Aquinas -- Summa Theologica
