into the hands of some children of God who are not in the habit of rising early, I make a few more remarks on the subject. I. It might be asked, how much time shall I allow myself for rest? The answer is, that no rule of universal application can be given, as all persons do not require the same measure of sleep, and also the same persons, at different times, according to the strength or weakness of their body, may require more or less. Females also, being generally weaker in body, require more sleep than males. Yet, from what I can learn, it is the opinion of medical persons, that men in health do not require more than between six and seven hours sleep, and females no more than between seven and eight hours; so that it would be rather an exception, for a man to require more than seven and a woman more than eight hours. But my decided advice, at the same time, is, that children of God should be careful not to allow themselves too little sleep, as there are few men who can do with less than six hours sleep, and yet be well in body and mind, and few females who can do with less than seven hours. Certain it is that for a long time, as a young man before I went to the university, I went to bed regularly at ten and rose at four, studied hard, and was in good health; and certain also, that since I have allowed myself only about seven hours, from the time of my visit at Plymouth in Oct. 1839, I have been much better in body, and in my nerves in particular, than when I was eight or eight hours and a half in bed. II. If it be asked, but why should I rise early? The reply is, to remain too long in bed is 1. waste of time, which is unbecoming a saint, who is bought by the precious blood of Jesus, with his time and all he has, to be used for the Lord. If we sleep more than is needful for the refreshment of the body, it is wasting the time with which the Lord has intrusted us as a talent, to be used for His glory, for our own benefit, and the benefit of the saints and the unbelievers around us. 2. To remain too long in bed injures the body. Just as when we take too much food, we are injured thereby, so as it regards sleep. Medical persons would readily allow, that, the lying longer in bed than is needful for the strengthening of the body, does weaken it. 3. It injures the soul. The lying too long in bed, not merely keeps us from giving the most precious part of the day to prayer and meditation, but this sloth leads also to many other evils.--Any one need but make the experiment of spending one, two, or three hours in prayer and meditation before breakfast, either in his room, or with his Bible in his hand in the fields, and he will soon find out the beneficial effect which early rising has upon the outward and inward man. I beseech all my brethren and sisters into whose hand this may fall, and who are not in the habit of rising early, to make the trial, and they will praise the Lord for having done so.
