In a sermon entitled, The Sin and Folly of Depending on Future Time, Jonathan Edwards writes the following:
"Inquire, whether you would not much less meddle with the concerns of others, and be much more employed with your own hearts, if each day you had no dependence on living another day. If you were sensible that you had had no other day to depend upon than this, you would be sensible that you had great affairs of your own to attend to. You would find a great deal of business at home between God and your own soul; and considering that you cannot depend on another day, it would seem to you that you have but a short time in which to do it, and that therefore you have need to be much engaged. You would say as Christ did, I must work while the day lasts, for the night cometh, wherein no man can work (see John 9:4). You would find so much to be done, and so much difficulty in doing it, that you would have little leisure, and little heart, to intermeddle with the business of others. Your business would be confined to a much narrower compass. You would have so much to do at home in your closets, and with your own hearts, that you would find no occasion to go abroad for intermeddling business to fill up your time."
