And while the blindness is primarily in regard to spiritual and religious truths, it is not confined to these, but wherever spiritual blindness has fallen, the whole of a man's knowledge will suffer. There will be blindness to the highest philosophy, to the true basis and motive of morals, to true psychology, to the noblest poetry. All will be of the earth, earthy. You cannot strike religion out of men's thoughts, as you might take a stone out of a wall and leave the wall standing; you take out foundation and mortar, and make a ruinous heap.
I know, of course, that there may be much mental activity without any perception of spiritual realities, but all knowledge which is not purely mathematical or physical suffers by the absence of such perception. All this blindness is caused by sin.
Christ is the giver of spiritual sight. He restores the faculty by taking away the hindrance to its exercise. Further, He gives sight because He gives light.
But turn to facts of experience, and consider the mental apathy of heathenism as contrasted with the energy of mind within the limits of Christendom. Greece, of course, is a brilliant exception, but even there (1) what of the conceptions of God? (2) what of the effect of the wise on the mass of the nation? Think of the languid intellectual life of the East. Think of the energy of thought which has been working within the limits of Christianity. Think of Christian theology compared with the mythologies of idolatry. And the contrast holds not only in the religious field but all over the field of thought.
There is no such sure way of diffusing a culture which will refine and strengthen all the powers of mind as to diffuse the knowledge of Jesus, and to make men love Him. In His light they will see light.
To know Him and to keep company with Him is 'a liberal education,' as is seen in many a lowly life, all uninfluenced by what is called learning, but enriched with the finest flowers of 'culture,' and having gathered them all in Christ's garden.
Christ is the true light; in Him do we see. Without Him, what is all other knowledge? He is central to all, like genial heat about the roots of a plant. There is other knowledge than that of sense; and for the highest of all our knowledge we depend on Him who is the Word. In that region we can neither observe nor experiment. In that region facts must be brought by some other means than we can command, and we can but draw more or less accurate deductions from them. Logic without revelation is like a spinning-machine without any cotton, busy drawing out nothing. Here we have to listen. 'The entrance of Thy words giveth light.' Your God shall come and save you; then, by that divine coming and saving, 'the eyes of the blind shall be opened, and the ears of the deaf shall be unstopped.'
II. Christ as the Restorer of the Powers of Action.
Again turn to heathenism, see the apathetic indolence, the unprogressive torpor, 'Better fifty years of Europe than a cycle of Cathay.' Sin lames for service of God; it leaves the lower nature free to act, and that freedom paralyses all noble activity.
