Nothing can possibly make up for the lack of secret communion with God, or the training and discipline of His school. "All the wisdom of the Egyptians" would not have qualified Moses for his future path. He might have pursued a most brilliant course through the schools and colleges of Egypt. He might have come forth laden with literary honors--his intellect stored with learning, and his heart full of pride and self-sufficiency. He might have taken out his degree in the school of man, and yet have to learn his alphabet in the school of God. Mere human wisdom and learning, how valuable soever in themselves, can never constitute any one a servant of God, nor equip him for any department of divine service. Such things may qualify unrenewed nature to figure before the world; but the man whom God will use must be endowed with widely-different qualifications--such qualifications as can alone be found in the deep and hallowed retirement of the Lord's presence. All God's servants have been made to know and experience the truth of these statements. Moses at Horeb, Elijah at Cherith, Ezekiel at Chebar, Paul in Arabia, and John at Patmos, are all striking examples of the immense practical importance of being alone with God. And when we look at the Divine Servant, we find that the time He spent in private was nearly ten times as long as that which He spent in public. He, though perfect in understanding and in will, spent nearly thirty years in the obscurity of a carpenter's house at Nazareth ere He made His appearance in public. And even when He had entered upon His public career, how oft did He retreat from the gaze of men, to enjoy the sweet and sacred retirement of the divine presence!
