And that is the only aim that corresponds to what and where I am and to what I need. I fall back upon the grandly simple old words, very dear to some of us, perhaps, by boyish associations, 'Man's chief end is to glorify God, and (so) to enjoy Him for ever.' 'Unto Godliness' is to be the aim of every true life, and it is the only aim which corresponds to our circumstances and our relations, our powers and possibilities.
II. Notice the discipline which such an aim demands.
'Exercise thyself.' Now, I have no doubt that the bulk of my hearers know that the word here rendered 'exercise' is drawn from the athlete's training-ground, and is, in fact, akin to the word which is transported into English under the form 'gymnasium.' The Apostle's notion is that, just as the athlete, racer, or boxer goes through a course of training, so there is a training as severe, necessary for the godliness which Paul regards as the one true aim of life.
You Christian people ought to train your spirits at least as carefully as the athlete does his muscles. There are plenty of people, calling themselves Christians, who never give one-hundredth part as much systematic and diligent pains to fulfil the ideal of their Christian life as men will take to learn to ride a bicycle or to pull the stroke oar in a college boat. The self-denial and persistence and concentration which are freely spent upon excellence in athletic pursuits might well put to shame the way in which Christians go about the task of 'doing' their religion.
I suppose there never was a time, in England's history at any rate, whatever it may have been in Greece, when modern instances might give more point to an old saw than to-day does for this text, when athletic sports of all kinds are taking up so much of the time and the energy of our young men. I do not want to throw cold water on that, but I do say it is a miserable thing to think that so many professing Christians will give a great deal more pains to learn to play lawn tennis than ever they did to learn to be good, Christian people.
'Exercise thyself unto godliness.' Make a business of living your Christianity. Be in earnest about it. A tragically large number of professing Christians never were in earnest about mending themselves. And that is why they are so far, far behind. 'Exercise thyself.' You say, How?
'Well, I say, first of all, concentration. 'This _one_ thing I do.' That does not mean narrowing, because this 'one thing' can be done by means of all the legitimate things that we have to do in the world. Next Friday, when you go on 'Change, you can be exercising yourself to godliness there. Whatever may be the form of our daily occupation, it is the _gymnasium_ where God has put us to exercise our muscles in, and so to gain 'the wrestling thews that throw the world.' 'Be strong in the Lord, and in the power of His might.' The concentration for which I plead does not shut us out from any place but the devil's wrestling-ground. All that is legitimate, all that is innocent, may be made a means for manifesting and for increasing our godliness. Only you have to take God with you into your life, and to try, more and more consciously, to make Him the motive-power of all that you do. Then the old saying which is profoundly true as it was originally meant, and has of late years been so misused as to become profoundly false, will be true again, '_Laborare est orare_.' Yes! it is; if worship underlies the work, but not else.
Again I say, exercise yourselves by abstinence. How many things did the athlete at Corinth do without in his training? How many things do prizefighters and rowing men do without when in training to-day? How rigidly, for a while at any rate, they abstain--whether they recompense themselves afterwards or not has nothing to do with my present purpose. And is it not a shame that some sensual man shall, for the sake of winning a medal or a cup, be able gladly to abandon the delights of sense--eating, drinking, and the like--and content himself with a hermit's Spartan fare, and that Christian people so seldom, and so reluctantly, and so partially turn away from the poisoned cups and the indigestible dainties which the world provides for them? I think that any Christian man who complains of the things which he is shut out from doing if he is to cultivate the godliness which should be his life need only go to any place where horse-jockeys congregate to get a lesson that he may well lay to heart. 'Exercise thyself,' for it is unto godliness.
