Now remember that Christ's demand of self-surrender, self-sacrifice, continuous effort, rigid limitation, does not come from any mere false asceticism, but is inevitable in the very nature of the case, and is made also by all worthy work. How much every one of us has had to shear off our lives, how many tastes we have had to allow to go ungratified, how many capacities undeveloped, in how many directions we have had to hedge up our way, and not do, or be this, that, or the other; if we have ever done anything in any direction worthy the doing! Concentration and voluntary limitation, in order to fix all powers on the supreme aim which judgment and conscience have enjoined is the condition of all excellence, of all sanity of living, and eminently of all Christian discipleship. III. Further, note the failures. The tower of the rash builder stands a gaunt, staring ruin. Whosoever throws himself upon great undertakings or high aims, without a deliberate forecast of the difficulties and sacrifices they involve, is sure to stop almost before he has begun. Many a man and woman leaves the starting-point with a rush, as if they were going to be at the goal presently, and before they have run fifty yards turn aside and quietly walk out of the course. I wonder how many of you began, when you were lads or girls, to study some language, and stuck before you had got through twenty pages of the grammar, or to learn some art, and have still got the tools lying unused in a dusty corner. And how many of you who call yourselves Christians began in the same fashion long ago to run the race? 'Ye did run well.' What did hinder you? What hindered Atalanta? The golden apples that were flung down on the path. Oh, the Church is full of these abortive Christians; ruins from their beginning, standing gaunt and windowless, the ground-plan a great palace, the reality a hovel that has not risen a foot for the last ten years. I wonder if there are any stunted Christians of that sort in this congregation before me, who began under the influence of some impulse or emotion, genuine enough, no doubt, but who had taken no account of how much it would cost to finish the building. And so the building is not finished, and never will be.
