Intemperance in eating and drinking, intemperance in labor, intemperance in almost everything, exists on every hand. Those who make great exertions to accomplish just so much work in a given time, and continue to labor when their judgment tells them they should rest, are never gainers. They are living on borrowed capital. They are expending the vital force which they will need at a future time. And when the energy they have so recklessly used is demanded, they fail for want of it. The physical strength is gone, the mental powers fail. They realize that they have met with a loss, but do not know what it is. Their time of need has come, but their physical resources are exhausted. Everyone who violates the laws of health must sometime be a sufferer to a greater or less degree. God has provided us with constitutional force, which will be needed at different periods of our life. If we recklessly exhaust this force by continual overtaxation, we shall sometime be losers. Our usefulness will be lessened, if not our life itself destroyed.
