Some people, in order to discover God, read books. But there is a great book: the very appearance of created things. Look above you! Look below you! Read it. God, whom you want to discover, never wrote that book with ink. Instead, He set before your eyes the things that He had made. Can you ask for a louder voice than that?

Seeing is the property of our eyes. But we also use this word in other senses, when we apply the power of vision to knowledge generally. We do not say 'Hear how that flashes', or 'Smell how bright that is', or 'Taste how that shines' or 'Touch how that gleams'. Of all these things we say 'see'. But we say not only 'See how that light shines', which only the eyes can perceive, but also 'See how that sounds, see what smells, see what tastes, see how hard that is'. So the general experience of the senses is the lust, as scripture says, of the eyes, because seeing is a function in which eyes hold the first place but other senses claim the word for themselves by analogy when they are exploring any department of knowledge.

Time takes no holiday. It does not roll idly by, but through our senses works its own wonders in the mind. Time came and went from one day to the next; in its coming and its passing it brought me other hopes and other memories. [quoted in Peter Brown, Augustine of Hippo, p. 54]

Understand that I am already a Christian.” Whereto he answered, “I will not believe it, nor will I rank you among Christians, unless I see you in the Church of Christ.” The other, in banter, replied, “Do walls then make Christians?

Life is a misery, death an uncertainty. Suppose it steals suddenly upon me, in what state shall I leave this world? When can I learn what I have here neglected to learn? Or is it true that death will cut off and put an end to all care and all feeling? This is something to be inquired into. But no, this cannot be true. It is not for nothing, it is not meaningless that all over the world is displayed the high and towering authority of the Christian faith. Such great and wonderful things would never have been done for us by God, if the life of the soul were to end with the death of the body. Why then do I delay? Why do I not abandon my hopes of this world and devote myself entirely to the search for God and for the happy life?
