The Great Value of Withstanding Temptations

Fire tempers iron and temptation steels the just.  Often, we do not know what we can stand, but temptation shows us what we are.  Above all, we must be especially alert against the beginnings of temptation, for the enemy is more easily conquered if he is refused admittance to the mind and is met beyond the threshold when he knocks.

Imitation of Christ, Thomas à Kempis; Book I, Ch. 13.
