No definition of man is large enough to accommodate the facts of his nature, that does not embrace what he is without as well as what he is within, what he is objectively as well as what he is subjectively. It must not only embrace the intellect, but the truth which it thinks; not only the will, but the right which corresponds to it; not only the eye, but the light which gives it meaning; not only the ear, but the sound which matches it; not only the lungs, but the atmosphere to which they are correlated. Human nature is dually constituted, so that the larger half of itself is outside of itself. Illustrations of the same duality of constitution may be found on a limited scale in the organic and in the inorganic worlds. The greater half of the oak is not in the life germ of the acorn, but in the elements of the soil and the sky which environ it. The larger part of the fish is in the ocean which surrounds it. Most of the fuel which makes the heat in the grate is not in the carbon of the coal, but in the oxygen of the air which fills the room. I. The possession of a will and the capacity for choice make man a moral being. Man’s will is bounded on every side by the laws of God. These laws are only another name for God’s will. Man is made in God’s image and has a will, as far as it goes, just like God’s will. By choosing to act and to move along the lines of law which gather from every whither about his will, he finds he can go somewhere, that he can leave the narrow, provincial, and local neighborhood of ease and sense and subjection, and find his life in that broad realm of freedom, that belongs to him as a thinking and willing being. At the termini of some railroads there are huge contrivances called turntables. They are constructed of immense timbers and balanced on pivots. They are large enough to accommodate the full length of a steam engine. Iron rails are laid across these tables, of the same size and the same distance apart as the rails which make up the lines of the main track. When the train comes in from the far interior, the engine is run out on one of these tables and turned round, so that the headlight faces the main track again. Before the engine is ready to leave the short track, however, the rails on the turntable must exactly correspond to the rails on the main road. Then the engineer pulls the throttle, and the great locomotive rolls past the circumference of its pivoted and temporary resting place into commerce with the railways of the globe. Imagine railway lines coming together about such a revolving table from all the earth, so that an engine could pass from this circular platform toward any quarter of the globe, the only condition being that the short track on the table correspond to the rails of the long track on which it was proposed for the engine to run, and you have an illustration, which in some degree helps us to understand the relation of man’s will to the laws of God.
