A Christian should have a well [of love] which cannot be dried up or exhausted, even if his charity is poured out like water into sand.—Martin Luther, Sermon on Trinity 4, 1533
So often Our Lord's own words are both far fiercer and far more tolerable than those of the theologians. He says nothing about guarding against earthly loves for fear we might be hurt. He says something that cracks like a whip about trampling them all under foot the moment they hold us back from following Him.—C. S. Lewis, Business of Heaven, p. 177.
