We might be disposed to think that the very moment the divine commission was given to Moses, his reply would be, Here am I, or, Lord, what wilt Thou have me to do? But no; he had yet to be brought to this. Doubtless, he was affected by the remembrance of his former failure. If a man acts in anything without God, he is sure to be discouraged, even when God is sending him. "And Moses said unto God, 'Who am I that I should go unto Pharaoh, and that I should bring forth the children of Israel out of Egypt?'" (Ver. 11.) This is very unlike the man who, forty years before, "supposed that his brethren would have understood how that God by his hand would deliver them." Such is man!--at one time too hasty; at another time too slow. Moses had learnt a great deal since the day in which he smote the Egyptian. He had grown in the knowledge of himself, and this produced diffidence and timidity. But then he manifestly lacked confidence in God. If I am merely looking at myself, I shall do "nothing;" but if I am looking at Christ, "I can do all things." Thus, when diffidence and timidity led Moses to say, "Who am I?" God's answer was, "Certainly _I_ will be with thee." (Ver. 12.) This ought to have been sufficient. If God be with me, it makes very little matter who I am, or what I am. When God says, "I will send thee," and "I will be with thee," the servant is amply furnished with divine authority and divine power; and he ought, therefore, to be perfectly satisfied to go forth.
But Moses puts another question; for the human heart is full of questions. "And Moses said unto God, 'Behold, when I come unto the children of Israel and shall say unto them, The God of your fathers hath sent me unto you; and they shall say to me, What is His name? what shall I say unto them?'" It is marvelous to see how the human heart reasons and questions, when unhesitating obedience is that which is due to God; and still more marvelous is the grace that bears with all the reasonings and answers all the questions. Each question seems but to elicit some new feature of divine grace.
"And God said unto Moses, 'I AM THAT I AM;' and He said, 'Thus shalt thou say unto the children of Israel, I AM hath sent me unto you.'" (Ver. 14.) The title which God here gives Himself is one of wondrous significancy. In tracing through Scripture the various names which God takes, we find them intimately connected with the varied need of those with whom He was in relation. "Jehovah-jireh" (the Lord will provide), "Jehovah-nissi" (the Lord my banner), "Jehovah-shalom" (the Lord send peace), "Jehovah-tsidkenu" (the Lord our righteousness),--all these His gracious titles are unfolded to meet the necessities of His people; and when He calls Himself "I AM," it comprehends them all. Jehovah, in taking this title, was furnishing His people with a blank check, to be filled up to any amount. He calls Himself "I AM," and faith has but to write over against that ineffably precious name whatever we want. God is the only significant figure, and human need may add the ciphers. If we want life, Christ says, "I AM the life;" if we want righteousness, He is "THE LORD OUR RIGHTEOUSNESS;" if we want peace, "He is our peace;" if we want "wisdom, sanctification, and redemption," He "is made" all these "unto us." In a word, we may travel through the wide range of human necessity, in order to have a just conception of the amazing depth and fullness of this profound and adorable name, "I AM."
What a mercy to be called to walk in companionship with One who bears such a name as this! We are in the wilderness, and there we have to meet with trial, sorrow, and difficulty; but, so long as we have the happy privilege of betaking ourselves, at all times and under all circumstances, to One who reveals Himself in His manifold grace, in connection with our every necessity and weakness, we need not fear the wilderness. God was about to bring His people across the sandy desert, when He disclosed this precious and comprehensive name; and although the believer now, as being endowed with the Spirit of adoption, can cry, "Abba, Father," yet is he not deprived of the privilege of enjoying communion with God in each and every one of those manifestations which He has been pleased to make of Himself. For example, the title "God" reveals Him as acting in the solitariness of His own being, displaying His eternal power and Godhead in the works of creation. "The Lord God" is the title which He takes in connection with man. Then, as "the Almighty God," He rises before the view of His servant Abraham, in order to assure his heart in reference to the accomplishment of His promise touching the seed. As "Jehovah," He made Himself known to Israel, in delivering them out of the land of Egypt, and bringing them into the land of Canaan.
