Now we may feel disposed to ask, How could the urgent demand for workmen ever be met if all need such protracted training, in secret, ere they come forth to their work? This is the Master's care--not ours. He can provide the workmen, and He can train them also. This is not man's work. God alone can provide and prepare a true minister. Nor is it a question with Him as to the length of time needful for the education of such an one. We know He could educate him in a moment, if it were His will to do so. One thing is evident, namely, that God has had all His servants very much alone with Himself, both before and after their entrance upon their public work; nor will any one ever get on without this. The absence of secret training and discipline will necessarily leave us barren, superficial, and theoretic. A man who ventures forth upon a public career ere he has duly weighed himself in the balances of the sanctuary, or measured himself in the presence of God, is like a ship putting out to sea without proper ballast: he will doubtless overset with the first stiff breeze. On the contrary, there is a depth, a solidity, and a steadiness flowing from our having passed from form to form in the school of God, which are essential elements in the formation of the character of a true and effective servant of God. Hence, therefore, when we find Moses, at the age of forty years, taken apart from all the dignity and splendor of a court, for the purpose of spending forty years in the obscurity of a desert, we are led to expect a remarkable course of service; nor are we disappointed. The man whom God educates is educated, and none other. It lies not within the range of man to prepare an instrument for the service of God. The hand of man could never mould "a vessel meet for the Master's use." The One who is to use the vessel can alone prepare it; and we have before us a singularly beautiful sample of His mode of preparation.
