But all this variety of impulses and complicated experiences need the co-operation of the man himself if they are to reach their highest results in him. If he is simply recipient of these external forces acting upon him, they will shape him indeed, but he will be a poor creature. Life does not make men unless men take the command of life, and he who lets circumstances and externals guide him, as the long water weeds in a river are directed by its current, will, from the highest point of view, have experienced the variations of a lifetime in vain. No doubt each of our experiences has its own immediate and lower purpose to serve, and these purposes are generally accomplished, but beyond these each has a further aim which is not reached without diligent carefulness and persistent effort on our parts. If we would be sure of what it is to suffer life's experiences in vain, we have but to ask ourselves what life is given us for, and we all know that well enough to be able to judge how far we have used life to attain the highest ends of living. We may put these ends in various ways in our investigation of the results of our manifold experiences. Let us begin with the lowest--we received life that we might learn truth, then if our experience has not taught us wisdom it has been in vain. It is deplorable to have to look round and see how little the multitude of men are capable of forming anything like an independent and intelligent opinion, and how they are swayed by gusts of passion, by blind prejudice, by pretenders and quacks of all sorts. It is no less sad for us to turn our eyes within and discover, perhaps not without surprise and shame, how few of what we are self-complacent enough to call our opinions are due to our own convictions. If we ever are honest enough with ourselves to catch a glimpse of our own unwisdom, the question of our text will press heavily upon us, and may help to make us wiser by teaching us how foolish we are. An infinite source of wisdom is open to us, and all the rich variety of our lives' experiences has been lavished on us to help us, and what have we made of it all? But we may rise a step higher and remember that we are made moral creatures. Therefore, whatever has not developed infant potentialities in us, and made them moral qualities, has been experienced in vain. 'Not enjoyment and not sorrow is our destined end and way.' Life is meant to make us love and do the good, and unless it has produced that effect on us, it has failed. If this be true, the world is full of failures, like the marred statues in a bad sculptor's studio, and we ourselves have earnestly to confess that the discipline of life has too often been wasted upon us, and that of us the divine complaint from of old has been true: 'In vain have I smitten thy children, they have received no correction.'
