The shadow is a fit emblem of human life. From the hour it falls on the dial it moves round the little circle until the sun sinks, when in a moment it is gone. A few hours past, and its work is done. The shadow thrown by the brightest sunshine must vanish when the night comes. Thus it is with life.
I. God does not speak to us through nature without a purpose. We are not to ponder in our hearts on the analogy between human life and nature in its various phases for the pleasure of indulging in sentimental feelings. When Moses mused on the shortness of life, his prayer was, "So teach us to number our days, that we may apply our hearts unto wisdom." Life is short, so we must seek for wisdom to make the most of it. No more is required than that every man should do his best with the hours entrusted to his care.
II. The thought of life's shortness should lead us to value time more highly. Our short life on earth should be a life of work, for we shall have all eternity to rest in. Learn to value time, first, because you have the work your "hand finds" to accomplish, and, secondly, because you have to "work out your own salvation." The great lesson which the frailty and shortness of life should teach us is the importance of preparing for the eternity beyond.
