That constant, unnoticed progress has an end. Our life is a definite period, having a bounded past behind it, a present, and a bounded future before it. We have a sandglass and it runs out. We are like men sliding down a rope or hauling a boat towards a fixed point. The sea is washing away our sandy island, and is creeping nearer and nearer to where we stand, and will wash over us soon. No cries, nor prayers, nor wishes will avail. It is vain for _us_ to say, 'Sun! stand thou still!' II. Therefore our chief care should be to finish our work in our day. Joshua had his day lengthened; we can come to the same result by crowding ours with service. What is the purpose of life? Is it a shop? or a garden? a school? No. Our 'chief end' is to become like God and a little to help forward His cause. All is intended to develop character; all life is disciplinary. God's purpose should be our desire. That desire should mould all our thoughts and acts. There should be no mere sentimental regrets for the past, but the spirit of consecration should affect our thoughts about it. There should be penitence, thankfulness, not vain mourning over what is gone. There should be no waste or selfish use of the present. What is it given us for but to use for God? Strenuous work is the true way to lengthen each day. Time is infinitely elastic. The noblest work is to do 'the works of Him that sent me.' There should be no care for the future. It is in His hand. There will be room in it for doing all His will. 'Lord, it belongs not to my care, Whether I die or live.' III. If so, the passing day will have results that never pass. Joshua's day was long enough for his work, and that work was a victory which told on future generations. So life, short as it is, will be long enough for all that we have to do and learn and be. Christ's servant is immortal till his work is done. God gives every man time enough for his salvation. What may we bring out of life? Character, Christ-likeness, thankful memories, union with God, capacity for heaven. The transient leaves the abiding. The flood foams itself away, but deposits rich soil on the plain. IV. Thus the passing away of what must pass may become a joy. Why should we be sad? There are reasons enough, as many sad, lonely hearts among us know too well To some men dark thoughts of death and judgment make the crumbling away of life too gloomy a fact to be contemplated, but it may and should be calm joy to us that the weary world ends and a blessed life begins. We may count the moments and see them pass, as a bride watches the hours rolling on to her marriage morning; not, indeed, without tremor and sadness at leaving her old home, but yet with meek hope and gentle joy. It is possible for men to see that life is but 'as a shadow that declineth,' and yet to be glad. By faith in Christ, united to 'Him Who is for ever and ever,' our souls shall 'triumph over death and thee, O time.'
