O Lord GOD, thou hast begun to shew thy servant thy greatness, and thy mighty hand: for what God is there in heaven or in earth, that can do according to thy works, and according to thy might?
God is the source of all the power there is. There isn’t any power anywhere that doesn’t have God as its source, whether it be the power of the intellect, of the spirit, of the soul, of dynamite, of the storm or of magnetic attraction. Wherever there is any power at all, God is the author of it. And the source of anything has to be greater than that which flows out of it.
If you pour a quart of milk out of a can, that can has to be equal to or greater than a quart. The can has to be as big as or bigger than that which comes out of it. The can may contain several gallons, though you may pour out only a quart. The source has to be as big or bigger than that which comes out of it. So if all the power there is came from God—all the power—therefore, God’s power must be equal to or greater than all the power there is. AOGII074-075
Lord, why do we worry and fear so much when we are the dear children of the One who has such power? Strengthen me today with the promise of Your power. Amen. 
23–25 Although Moses was the great lawgiver and the ruler of Israel, he addresses his God as the “Sovereign Lord” and regards himself as his “servant.” Moses realized that he had only begun to comprehend his great God’s majesty because God had only begun to manifest himself to Moses and his people. The phrase “your greatness and your strong hand” refers to Yahweh’s awe-inspiring character and his impressive interventions in Israel’s behalf.
Moses breaks out in praise of his incomparable God because there were no gods like him. His question, “For what god is there in heaven or on earth …,” is a rhetorical question asked for emphasis. Moses was addressing the “marketplace of ideas” that existed in his day. He was referring to the conception of pagans (and certain Israelites) for the sake of argument. He was not granting the existence of other powerful gods and concluding that Yahweh is the winner out of many; rather, he was emphasizing that Yahweh is unique and unparalleled, the one and only true God (cf. 4:32–39). Moses pleaded (3:23) for God to allow him to witness personally the fulfillment of God’s promise to provide Israel with a land (Ge 12:1; 13:14–17; 15:18–21; 17:8; 26:3–4; 48:3–4).
3:24 O Lord God: The Hebrew has the word for “Lord” or “Master” followed by the personal name of God, Yahweh. This phrase indicates the depth of Moses’ relationship with the Lord (9:26). what god is there … mighty deeds: Moses began his prayer with praise for God’s holiness and power (Ex. 15:11). God is incomparable; there was none like Him (Is. 40:25, 26).
