“Redeeming the time.” Eph. 5:16.
1. “See that ye walk circumspectly,” says the Apostle in the preceding verse, “not as fools, but as wise men, redeeming the time;” saving all the time you can for the best purposes; buying up every fleeting moment out of the hands of sin and Satan, out of the hands of sloth, ease, pleasure, worldly business; the more diligently, because the present “are evil days,” days of the grossest ignorance, immorality, and profaneness.
2. This seems to be the general meaning of the words. But I purpose, at present, to consider only one particular way of redeeming the time,” namely, from sleep.
3. This appears to have been exceeding little considered, even by pious men. Many that have been eminently conscientious in other respects, have not been so in this. They seemed to think it an indifferent thing, whether they slept more or less; and never saw it in the true point of view, as an important branch of Christian temperance.
That we may have a more just conception hereof, I will endeavour to show,
I. What it is to “redeem the time” from sleep.
II. The evil of not redeeming it. And
III. The most effectual manner of doing it.
I. 1. And, First, What is it to “redeem the time” from sleep It is, in general, to take that measure of sleep every night which nature requires, and no more; that measure which is the most conducive to the health and vigour both of the body and mind.
2. But it is objected, “One measure will not suit all men; — some require considerably more than others. Neither will the same measure suffice even the same persons at one time as at another. When a person is sick, or, if not actually so, yet weakened by preceding sickness, he certainly wants more of this natural restorative, than he did when in perfect health. And so he will when his strength and spirits are exhausted by hard or long-continued labour.”
3. All this is unquestionably true, and confirmed by a thousand experiments. Whoever, therefore, they are that have attempted to fix one measure of sleep for all persons did not understand the nature of the human body, so widely different in different persons; as neither did they who imagined that the same measure would suit even the same person at all times. One would wonder, therefore, that so great a man as Bishop Taylor should have formed this strange imagination; much more, that the measure which he has assigned for the general standard should be only three hours in four-and-twenty. That good and sensible man, Mr. Baxter, was not much nearer the truth; who supposes four hours in four and twenty will suffice for any man. I knew an extremely sensible man, who was absolutely persuaded that no one living needed to sleep above five hours in twenty-four. But when he made the experiment himself, he quickly relinquished the opinion. And I am fully convinced, by an observation continued for more than fifty years, that whatever may be done by extraordinary persons, or in some extraordinary cases (wherein persons have subsisted with very little sleep for some weeks, or even months,) a human body can scarce continue in health and vigour, without at least, six hours’ sleep in four-and-twenty. Sure I am, I never met with such an instance: I never found either man or woman that retained vigorous health for one year, with a less quantity of sleep than this.
4. And I have long observed, that women, in general, want a little more sleep than men; perhaps, because they are, in common of a weaker, as well as a moister, habit of body. If, therefore, one might venture to name one standard, (though liable to many exceptions and occasional alterations,) I am inclined to think this would come near to the mark: Healthy men, in general, need a little above six hours’ sleep, healthy women, a little above seven, in four-and-twenty. I myself want six hours and a half, and I cannot well subsist with less.
5. If anyone desires to know exactly what quantity of sleep his own constitution requires, he may very easily make the experiment which I made about sixty years ago: I then waked every night about twelve or one, and lay awake for some time. I readily concluded that this arose from my lying longer in bed than nature required. To be satisfied, I procured an alarum, which waked me the next morning at seven; (near an hour earlier than I rose the day before,) yet I lay awake again at night. The second morning I rose at six; but, notwithstanding this, I lay awake the second night. The third morning I rose at five; but, nevertheless, I lay awake the third night. The fourth morning I rose at four; (as, by the grace of God, I have done ever since;) and I lay awake no more. And I do not now lie awake (taking the year round) a quarter of an hour together in a month. By the same experiment, rising earlier and earlier every morning, may anyone find how much sleep he really wants.
II. 1. “But why should anyone be at so much pains What need is there of being so scrupulous Why should we make ourselves so particular What harm is there in doing as our neighbours do — suppose in lying from ten till six or seven in summer, and till eight or nine in winter”
