God had made a positive promise to Moses that for the space of a whole month He would feed the vast company in the wilderness with meat. Moses is then overtaken by a fit of unbelief, looks to the outward means, and is at a loss to know how the promise can be fulfilled. He looked to the creature instead of the Creator. But does the Creator expect the creature to fulfill His promise for Him? No; He who makes the promise always fulfills it by His own unaided omnipotence. If He speaks, it is done—done by Himself. His promises do not depend for their fulfillment upon the cooperation of the puny strength of man. We can immediately see the mistake that Moses made. And yet how routinely we do the same!
God has promised to supply our needs, and we look to the creature to do what God has promised to do; and then, because we perceive the creature to be weak and feeble, we indulge in unbelief. Why do we look in that direction at all? Will you look to the North Pole to gather fruits ripened in the sun? You would be acting no more foolishly in doing this than when you look to the weak for strength, and to the creature to do the Creator's work. Let us, then, put the question on the right footing. The ground of faith is not the sufficiency of the visible means for the performance of the promise, but the all-sufficiency of the invisible God, who will definitely do what He has said.
If after clearly seeing that the onus lies with the Lord and not with the creature we dare to indulge in mistrust, the question of God comes home forcefully to us: "Is the LORD's hand shortened?" May it also be that in His mercy the question will be accompanied by this blessed declaration: "Now you shall see whether my word will come true for you or not."
