In Moses' reply to this last objection, we are furnished with a fine statement of the Lord's paramount claim upon His people and all pertaining to them. "And Moses said, 'Thou must give us also sacrifices and burnt offerings, that we may sacrifice unto the Lord our God. Our cattle also shall go with us; _there shall not a hoof be left behind_: for thereof must we take to serve the Lord our God; and we know not with what we must serve the Lord until we come thither.'" (Ver. 25, 26.) It is only when the people of God take their stand, in simple childlike faith, upon that elevated ground on which death and resurrection set them, that they can have anything like an adequate sense of His claims upon them. "We know not with what we must serve the Lord until we come thither." That is, they had no knowledge of the divine claim, or their responsibility, until they had gone "three days' journey." These things could not be known amid the dense and polluted atmosphere of Egypt. Redemption must be known as an accomplished fact, ere there can be any just or full perception of responsibility. All this is perfect and beautiful. "If any man will do His will, he shall know of the doctrine." I must be up out of Egypt, in the power of death and resurrection, and then, but not until then, shall I know what the Lord's service really is. It is when we take our stand, by faith, in that "large room," that wealthy place into which the precious blood of Christ introduces us,--when we look around us and survey the rich, rare, and manifold results of redeeming love,--when we gaze upon the Person of Him who has brought us into this place, and endowed us with these riches, then we are constrained to say, in the language of one of our own poets,-- "Were the whole realm of nature mine, That were an offering far too small; Love so amazing, so divine, Demands my heart, my life, my all."
