Now let this be especially observed, that while we may here recognise a practical lesson to be learned, the wisest of us may also recognise it as a lesson we could not undertake to teach to ourselves. To oppose sin, when conscience and God's word warn us of its presence, is at least something definite and plain. But how to take the right attitude and bear the right mind towards this various, manifold, engrossing, wonderful human life, as it unfolds for us here--how shall that be done? Some have tried to answer by amputating large sections of human experience. But that is not the way. For, indeed, it is in human life itself--in this present, and, for the present, the only form of our existence--that we must take the right view of human life, and form the right mind about it. Moreover, our conditions are varying continually, from the state of the little child, open to every influence that strikes the sense, to the state of the old man, whom age is shutting up in a crippled and stunted existence. The just equipoise of soul for one stage of life, could it be attained, would not be the just equipoise for the next. The truth is, there is no ready-made theory here for any of us. All our attainments in it are tentative and provisional; which does not hinder, however, that they may be very real. When we believe in Christ we become aware that there is a lesson in this department to be learned, and we become willing, in a measure, to learn it. But we should learn little were it not for three great teachers that take us in hand. The first is the inevitable conflict with sin and temptation. The Christian must, at all events, strive against known sin, and he must hold himself ready to resist the onset of temptation, watching and praying. In this discipline he soon learns how sin is entangled for him with much that in other respects seems desirable or good; he learns that in rejecting sin he must forgo some things which on other accounts he gladly would embrace. It is often a painful conflict through which he has to pass. Now in seeking help from his Lord, and entering into the fellowship of the mind of Christ, he is not only strengthened to repel the sin, but also learns to submit willingly to any impoverishment or abridgement of earthly life which the conflict entails. He is taught in practice, now in one form, now in another, to count _all_ things but loss--to lower the overweening estimate of earthly treasure and let it go, dying to it with his dying Lord.
