The Christian is too sincere to play with ideas for their own sake. He takes no pleasure in the mere spinning of gossamer webs for display. All his beliefs are practical. They are geared into his life. By them he lives or dies, stands or falls for this world and for all time to come. From the insincere man he turns away.
The sincere plain man knows that the world is real. He finds it here when he wakes to consciousness, and he knows that he did not think it into being. It was here waiting for him when he came, and he knows that when he prepares to leave this earthly scene it will be here still to bid him good-bye as he departs. By the deep wisdom of life he is wiser than a thousand men who doubt. He stands upon the earth and feels the wind and rain in his face and he knows that they are real. He sees the sun by day and the stars by night. He sees the hot lightning play out of the dark thundercloud. He hears the sounds of nature and the cries of human joy and pain. These he knows are real. He lies down on the cool earth at night and has no fear that it will prove illusory or fail him while he sleeps. In the morning the firm ground will be under him, the blue sky above him and the rocks and trees around him as when he closed his eyes the night before. So he lives and rejoices in a world of reality.
With his five senses he engages this real world. All things necessary to his physical existence he apprehends by the faculties with which he has been equipped by the God who created him and placed him in such a world as this.
Now, by our definition also God is real. He is real in the absolute and final sense that nothing else is. All other reality is contingent upon His. The great Reality is God who is the Author of that lower and dependent reality which makes up the sum of created things, including ourselves. God has objective existence independent of and apart from any notions which we may have concerning Him. The worshipping heart does not create its Object. It finds Him here when it wakes from its moral slumber in the morning of its regeneration.
Another word that must be cleared up is the word reckon. This does not mean to visualize or imagine. Imagination is not faith. The two are not only different from, but stand in sharp opposition to, each other. Imagination projects unreal images out of the mind and seeks to attach reality to them. Faith creates nothing; it simply reckons upon that which is already there.
God and the spiritual world are real. We can reckon upon them with as much assurance as we reckon upon the familiar world around us. Spiritual things are there (or rather we should say here) inviting our attention and challenging our trust.
Our trouble is that we have established bad thought habits. We habitually think of the visible world as real and doubt the reality of any other. We do not deny the existence of the spiritual world but we doubt that it is real in the accepted meaning of the word.
