Mira, eso del amor es una cosa de libros, algo que se ha inventado no más que para hablar y escribir de ello. Tonterías de poetas - Miguel de Unamuno

Conduct, practice, is the proof of doctrine, theory. "If any man will do His will — the will of Him that sent me," said Jesus, "he shall know of the doctrine, whether it be of God or whether I speak of myself" (John vii. 17); and there is a well known saying of Pascal: "Begin by taking holy water and you will end by becoming a believer." And pursuing a similar train of thought, Johann Jakob Moser, the pietist, was of the opinion that no atheist or naturalist had the right to regard the Christian religion as void of truth so long as he had not put it to the proof by keeping its precepts and commandments (Ritschl, Geschichte des Pietismus, book viii., 43).

To know something is to make this something that I know myself; but to avail myself of it, to dominate it, it has to remain distinct from myself.

To believe in God is to long for His existence and, further, it is to act as if he existed; it is to live by this longing and to make it the inner spring of our action. This longing or hunger for divinity begets hope, hope begets faith, and faith and hope beget charity. Of this divine longing is born our sense of beauty, of finality, of goodness.
