There is no good in making Christianity easy and pleasant; "Youth", or the better part of it, is more likely to come to a difficult religion than to an easy one. For some, the intellectual way of approach must be emphasized; there is need of a more intellectual laity. For them and for others, the way of discipline and asceticism must be emphasized; for even the humblest Christian layman can and must live what, in the modern world, is comparatively an ascetic life. Discipline of the emotions is even rarer, and in the modern world still more difficult, than discipline of the mind; some eminent lay preachers of "discipline" are men who know only the latter. Thought, study, mortification, sacrifice: it is such notions as these that should be impressed upon the young-- who differ from the young of other times merely in having a different middle-aged generation behind them. You will never attract the young by making Christianity easy; but a good many can be attracted by finding it difficult: difficult both to the disorderly mind and to the unruly passions.
