Oh how swiftly the glory of the world passes away! If only the lives of these men had been as admirable as their learning, their study and reading would have been to good purpose! But how many in this world care little for the service of God, and perish in their vain learning. Because they choose to be great rather than humble, they perish in their own conceit.
Thomas a KempisNo one is so good that he is immune from temptation. We will never be entirely free from it. . . . There is no order so holy, no place so secret where there will be no temptation.
Thomas a KempisAnyone who is not totally dead to himself will soon find that he is tempted and overcome by piddling and frivolous things. Whoever is weak in spirit, given to the flesh and inclined to sensual things can, but only with great difficulty, drag himself away from his earthly desires. Therefore he is often gloomy and sad when he is trying to pull himself away from them, and easily gives way to anger should someone attempt to oppose him.
