The same planes of existence are distinguishable in all ages since the flood, but Christ alone rose to the purely spiritual level. Israel as a nation might have so lived had true educational methods been followed. Israel falling, the offer was made to the Christian church. Age by age that body has refused to live a spiritual life, or, accepting the proffered gift, has attempted to rise without complying with the necessary conditions,—absolute faith in God’s Word and strict compliance with his commands. The Reformation again turned men’s eyes toward a spiritual education, and American Protestants had the best opportunity ever offered man to return to the original design of the Creator. Failure is again the verdict of the recording angel. Time hastens on, and the last gospel message is going to the world; but before _a people can be prepared for the setting up of Christ’s kingdom, they must be educated according to the principles of Christian education_, for this is _the foundation_ of all government as well as of all religion. What is Christian education? Since its object is the training of a human being for life eternal, and that existence is a spiritual life, the spiritual must be the predominating feature of the education. When the spiritual leads, the intellectual and physical take their proper positions. The inner or spiritual man feeds only upon truth, absolute truth; not theory nor speculation, but truth. “Thy word is truth.” _The Word of God must then be the basis_ of all Christian education, the science of salvation the central theme. [Sidenote: The test] Since God reveals his character in two ways, in his Word and in his works, the Bible must be the first book in Christian education, and the book of nature next. Many educators have seen the value of the book of nature, and to-day nature-study forms a large part of the course of instruction in all grades of schools. It may be asked, Is not this, then, Christian education? We reply, Does it restore in men the image of God? If so, it passes the test. But it can not be said to do this, and therefore it falls short. Wherein, then, lies the difficulty in modern nature-teaching, or the sciences in general? Read some of our modern text-books in science. They readily reveal the answer.
