“Bask in it. In spite of what the monks say, you can meet God without getting up early. You can meet God lounging in the pew. The hardship is a man-made device because man cannot exist without passion.”

Context: The mind of man will never be able to contemplate the being, perfections, and providence of God without meeting with inexplicable difficulties. We may find sufficient reason for acquiescing in the darkness which involves these great subjects, but we must never expect to see them set in a perfectly clear light. But notwithstanding this, we may know enough of the divine being, and of his moral government, to make us much better and happier beings than we could be without such knowledge; and even the consideration of the insuperable difficulties referred to above is not without its use, as it tends to impress the mind with sentiments of reverence, humility, and submission.

Eine mathematische Theorie ist nicht eher als vollkommen anzusehen, als bis du sie so klar gemacht hast, daß du sie dem ersten Manne erklären könntest, den du auf der Straße triffst.
Mathematical Problems (1900)
Context: An old French mathematician said: A mathematical theory is not to be considered complete until you have made it so clear that you can explain it to the first man whom you meet on the street. This clearness and ease of comprehension, here insisted on for a mathematical theory, I should still more demand for a mathematical problem if it is to be perfect; for what is clear and easily comprehended attracts, the complicated repels us.
