_Directions against sinful Excess of Sleep._
Of this, something is said already, chap. v. part i. and more afterwards in the directions against idleness. Therefore I shall say but little now. 1. I shall show you when sleep is excessive. 2. Wherein the sinfulness of it consisteth. 3. What to do for the cure of it.
I. Sleep is given us for the necessary remission of the animal operations, and of the labour or motion of the exterior parts, by the quieting of the senses, or shutting them up: that the natural and vital operations may have the less disturbance. It is necessary, 1. To our rest. 2. To concoction. Therefore weariness and want of concoction are the chief indications, to tell us how much is needful for us. Sleep is sinfully excessive, 1. When it is voluntarily more than is needful to our health. 2. When it is unseasonable, at forbidden times.
It is not all weariness or sleepiness that maketh sleep lawful or needful; for some is contracted by laziness, and some by many diseases, and some by other constant causes which make men almost always weary. Nor is it all want of concoction that sleep is a remedy for; some may be caused by excess of eating, which must be cured a better way; and many diseases may cause it, which require other cure. Therefore none must indulge excess upon these pretences. Nor must a present sense of the pleasure of sleeping, or the displeasure of waking, be the judge; for sluggards may think they feel it do them good, and that early rising doth them hurt; but this good is but their present ease, and this hurt is but a little trouble to their head, and eyes, and lazy flesh, just at the time. But reason and experience must judge what measure is best for your health, and that you must not exceed. To some five hours is enough; to the ordinary sort of healthful persons six hours is enough; to many weak, valetudinary persons seven hours is needful: to sick persons I am not to give directions.
2. Sleep is excessive at that particular time when it is unseasonable. As, 1. When we are asleep when we should be doing some necessary business which calls for present despatch. 2. Or when we should be hearing the sermon, or praying, in public or private. In a word, when it puts by any greater duty which we should then perform. As, when the disciples slept when Christ was in his agony: "Could ye not watch with me one hour? watch and pray, that ye enter not into temptation," Matt. xxvi. 40, 41.
It is a foppery and abuse of God and ourselves, to think that the breaking of our sleep is a thing that of itself pleaseth God; or that rising to pray at midnight is more acceptable to God than at another hour: usually such rising to pray is sinful, 1. Because it is done in an erroneous conceit that God accepts it better than in the day time. 2. Because they waste time in dressing and undressing. 3. Or else hurt their health by cold in the winter, and so lose more time than they redeem by shortening their lives. 4. And usually they are more drowsy and unfit. But to rise in the night to prayer is meet on some extraordinary occasion that calls for it; as to pray with or for a dying person, or such like; or when an extraordinary fervour and fitness prepareth us for it; and when we can stay up when we are up, and not lose time in going to bed again. But ordinarily that way is to be chosen that best redeemeth time; and that is, to consider just how much sleep our health requireth, and to take it if we can together without interruption, and to rise then and go about our duties. But those that cannot sleep in the night, must redeem that time as discretion shall direct them.
It is the voluntariness of the excess that the sinfulness principally consisteth in; and therefore the more voluntary the more sinful. In a lethargy or caros it is no sin: and when long watching, or some bodily weakness or distemper, make it almost unavoidable, the sin is the smaller: therefore in case of long watching and heaviness, Christ partly excused his disciples, saying, "The spirit is willing, but the flesh is weak," Matt. xxvi. 41. But when it cometh from a flesh-pleasing sloth, or from a disregard of any holy exercise that you are about, it is a grievous sin. And though it be involuntary just at the time, and you say, I would fain forbear sleeping now if I could; yet if it be voluntary remotely and in its causes, it is your sin. You would now forbear sleeping; but you would not forbear that pampering your body, and stuffing your guts, which causeth it; you would not deny the flesh its ease to avoid it.
