"Now, Moses kept the flock of Jethro, his father-in-law, the priest of Midian; and he led the flock to the backside of the desert, and came to the mountain of God, even to Horeb." (Exod. iii. 1.) Here, then, we have a marvelous change of circumstances. In Genesis, chapter xlvi. 31, we read, "Every shepherd is an abomination to the Egyptians;" and yet Moses, who was "learned in all the wisdom of the Egyptians," is transferred from the Egyptian court to the back of a mountain to tend a flock of sheep, and to be educated for the service of God. Assuredly, this is not "the manner of man." This is not nature's line of things. Flesh and blood could not understand this. We should have thought that Moses' education was finished when he had become master of all Egypt's wisdom, and that, moreover, in immediate connection with the rare advantages which a court life affords. We should have expected to find in one so highly favored, not only a solid and varied education, but also such an exquisite polish as would fit him for any sphere of action to which he might be called. But then, to find such a man with such attainments, called away from such a position to mind sheep at the back of a mountain, is something entirely beyond the utmost stretch of human thought and feeling. It lays prostrate in the dust all man's pride and glory. It declares plainly that this world's appliances are of little value in the divine estimation; yea, they are as "dung and dross," not only in the eyes of the Lord, but also in the eyes of all those who have been taught in His school. There is a very wide difference between human and divine education. The former has for its end the refinement and exaltation of nature; the latter begins with withering it up and setting it aside. "The natural man receiveth not the things of the Spirit of God; for they are foolishness unto him; neither can he know them, because they are spiritually discerned." (1 Cor. ii. 14.) Educate the "natural man" as much as you please, and you cannot make him a "spiritual man." "That which is born of the flesh is flesh; and that which is born of the Spirit is spirit." (John iii. 6.) If ever an educated "natural man" might look for success in the service of God, Moses might have counted upon it; he was "grown," he was "learned," he was "mighty in word and deed," and yet he had to learn something at "the backside of the desert" which Egypt's schools could never have taught him. Paul learnt more in Arabia than ever he had learnt at the feet of Gamaliel.[4] None can teach like God; and all who will learn _of_ Him must be alone _with_ Him.
