Thought from Today’s Old Testament Passage:
At last the actual call of God came Moses. It found him fulfilling a daily duty, keeping the sheep of his father-in-law. There can be no doubt that in the silent solitudes of the wilderness he had meditated on the condition of his people. Forty years, however, changes any man. The fiery impetuosity which characterized him at forty had matured into self-restraint and meekness at eighty.
In the mysterious fire manifestation God said to His servant certain things which lie at the foundation of all that is to follow. “I have seen… [I] have heard… I know… I am come… I will send thee.” Small wonder that Moses answered, “Who am I?” Does it seem strange that when God had spoken of Himself Moses should be conscious of himself? It is not strange. The light of the divine glory ever reveals man to himself. Hence the cry, “Who am I?” The answer was immediate and full of grace, “Certainly I will be with thee.” (G. Campbell Morgan, An Exposition of the Whole Bible (Fleming H. Revell Company, 1959), p. 35)
