Health and the belly, these are the two idols—especially with men of the present age, of whom I myself, a great sinner, am one—for which we live, and which we continually serve, even to the neglect of the duties of our Christian calling—for instance, to the neglect of the reading of the Word of God, which is sweeter than honey and honey-comb; to the neglect of prayer, that sweetest converse with God, and of the preaching of the Word of God. To walk a great deal for health, and to incite the appetite, to eat with appetite —such are the objects of the desires and aspirations of many of us. But through our frequent walks, through our fondness for food and drink, we shall find that one thing has been neglected, and another irrevocably missed, whilst others have not even entered into our minds; for can the time after a good dinner or supper be really a good time for any serious work! Even if we would like to occupy ourselves with work, the belly, full of food and drink, draws us away from it, and constrains us to rest, so that we begin to slumber over our work. What sort of work can it be? Indeed, there is nothing left, if it is after dinner, but to lie down and rest, and if it is after supper, after having prayed somehow or other (for a satiated man cannot even pray as he should), to go to bed and sleep—the miserable consequence of an overloaded stomach—until the next morning. And in the morning there is another sacrifice to your belly ready in the shape of a dainty breakfast. You get up, pray, of course not with your whole heart—since with our whole heart we can only eat and drink, walk, read novels, go to theatres, dance at evening parties, dress elegantly—and thus you pray, out of habit, carelessly, to save appearances, only as a form, without the essence of the prayer, without lively faith, without power, without any fervour in your petitions, praises, and thanks to the Lord God for His uncountable mercies, and then you hurry again to food and drink.
