Men act as though they depend on another day. They will do so if they set their hearts on the enjoyments of this life. I mean not, if they have any manner of affection to them. We may have some affection to the enjoyments of this world; otherwise they would cease to be enjoyments. If we might have no degree of rejoicing in them, we could not be thankful for them. Persons may in a degree take delight in earthly friends and other earthly enjoyments, but by setting our hearts on these things, by placing our happiness on them and letting out the current of our affections after them by turning and fixing our inclinations so much upon them that we cannot well enjoy ourselves without them, so that very much of the strength of the faculties of our minds is employed and taken up about these things, we show that we have our dependence on another day. The man who does this acts as though he depended on another day, yea many other days, in the world; for it is most evident that if the enjoyments of this world be of such a nature that they are not to be depended on for one day more, they are not worth the setting of our hearts upon them or the placing of our happiness in them. We may rejoice in the enjoyments of the world, but not in such a manner as to place the rest of our souls in them. We should conduct ourselves as those who have not the foundation of their joy shaken, though some appurtenances have failed. Our happiness as to the body of it, if I may so speak, should yet stand as on an immovable foundation.
