And then, still further, there is the fundamental condition of all; and that is, self-surrender. Our Lord lays this down in the most stringent terms in the words before my text, where He points to two directions in which that spirit is required to manifest itself. One is detachment from persons that are dearest, and even from one's own selfish life; the other is the acceptance of things that are most contrary to one's inclinations, against the grain, painful and hard to bear. And so we may combine these two in this statement: If any man is going to build a Christlike life he will have to detach himself from surrounding things and dear ones, and to crucify self by suppression of the lower nature and the endurance of evils. The preceding parable which is connected in subject with the text, the story of the great supper, and the excuses made for not coming to it, represents two-thirds of the refusals as arising from the undue love for, and regard to, earthly possessions, and the remaining third as arising from the undue love to, and regard for, the legitimate objects of affection. And these are the two chords that hold most of us most tightly. It is not Christianity alone, dear brethren, that says that if you want to do anything worth doing, you must detach yourself from outward wealth. It is not Christianity alone that says that, if you want to build up a noble life, you must not let earthly love dominate and absorb your energy; but it is Christianity that says so most emphatically, and that has best reason to say so.
Concentration is the secret of all excellence. If the river is to have any scour in it that will sweep away pollution and corruption, it must not go winding and lingering in many curves, howsoever flowery may be the banks, nor spreading over a broad bed, but you must straighten it up and make it deep that it may run strong. And if you will diffuse yourself all over these poor, wretched worldly goods, or even let the rush of your heart's outflow go in the direction of father and mother, wife and children, brethren and sisters, forgetting Him, then you will never come to any good nor be of use in this world. But if you want to be Christians after Christ's pattern, remember that the price of the building is rigidly to sacrifice self, 'to scorn delights and live laborious days,' and to keep all vagrant desires and purposes within rigid limits, and absolutely subordinated to Himself.
On the other hand, there is to be the acceptance of what is painful to the lower nature. Unpleasant consequences of duty have to be borne, and the lower self, with its appetites and desires, has to be crucified. The vine must be mercilessly pruned in tendrils, leaves, and branches even, though the rich sap may seem to bleed away to waste, if we are to grow precious grapes out of which may be expressed the wine of the Kingdom. We must be dead to much if we are to be alive to anything worth living for.
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.
