"Worst moment for the atheist"

"Rossetti makes the remark somewhere, bitterly but with great truth, that the worst moment for the atheist is when he is really thankful and has nobody to thank. The converse of this proposition is also true; and it is certain that this gratitude produced, in such men as we are here considering, the most purely joyful moments that have been known to man."

~G.K. Chesterton: St. Francis of Assisi, Chap. V.―Le Jongleur De Dieu.
