Is man, then, out of the arena altogether? Is he mere clay in the hands of the potter, a machine, a tool, an automaton? Yes and No. If he were a tool he would not be a man. If he were a man he would have something to do. One need not seek to balance what God does here, and what man does. But we shall attain to a sufficient measure of truth on a most delicate problem if we make a final appeal to the natural life. We find that in maintaining this natural life Nature has a share and man has a share. By far the larger part is done for us--the breathing, the secreting, the circulating of the blood, the building up of the organism. And although the part which man plays is a minor part, yet, strange to say, it is not less essential to the well being, and even to the being, of the whole. For instance, man has to take food. He has nothing to do with it after he has once taken it, for the moment it passes his lips it is taken in hand by reflex actions and handed on from one organ to another, his control over it, in the natural course of things, being completely lost. But the initial act was his. And without that nothing could have been done. Now whether there be an exact analogy between the voluntary and involuntary functions in the body, and the corresponding processes in the soul, we do not at present inquire. But this will indicate, at least, that man has his own part to play. Let him choose Life; let him daily nourish his soul; let him forever starve the old life; let him abide continuously as a living branch in the Vine, and the True-Vine Life will flow into his soul, assimilating, renewing, conforming to Type, till Christ, pledged by His own law, be formed in him. We have been dealing with Christianity at its most mystical point. Mark here once more its absolute naturalness. The pursuit of the Type is just what all Nature is engaged in. Plant and insect, fish and reptile, bird and mammal--these in their several spheres are striving after the Type. To prevent its extinction, to ennoble it, to people earth and sea and sky with it; this is the meaning of the Struggle for Life. And this is our life--to pursue the Type, to populate the world with it. Our religion is not all a mistake. We are not visionaries. We are not "unpractical," as men pronounce us, when we worship. To try to follow Christ is not to be "righteous overmuch." True men are not rhapsodizing when they preach; nor do those waste their lives who waste themselves in striving to extend the Kingdom of God on earth. This is what life is for. The Christian in his life-aim is in strict line with Nature. What men call his supernatural is quite natural.
