Moreover, if you do not steadily set your heart on Me, with a firm will to suffer everything for My sake, you will not be able to bear the heat of this battle or to win the crown of the blessed. You ought, therefore, to pass through all these things bravely and to oppose a strong hand to whatever stands in your way. For to him who triumphs heavenly bread is given, while for him who is too lazy to fight there remains much misery.
–Thomas à Kempis, The Imitation of Christ, translated by Aloysius Croft and Harold Bolton, 83
