I. "I will wait upon the Lord." At all times we are to be like servants who are standing in the presence of their master, and who are ready, the very moment He shall give His orders, to go to any place, to do any work. If, when you should be waiting for what God may call you to do, you are so taken up with your own worldly concerns that you cannot hear, what then? Will that be waiting upon the Lord? And see what is the promise attached to this. "They that wait upon the Lord shall renew their strength " that is, whatever He calls them to do, they shall have strength, time after time, to carry it on; the more work He gives them, the more power will He give them to do it with.
II. "That hideth His face from the house of Jacob." The house of Jacob means the Church militant; the house of Israel, the Church in heaven. When it seems as if we could not stand against temptation, when there is some besetting sin which overthrows us again and again, then it seems as if God were hiding His face from us. And David might well say, "Thou didst hide Thy face from me, and I was troubled." For then we are troubled indeed: when we have to cry out, "Save me, O God; for the waters are come in, even unto my soul." And what are we to do then? The text tells us we are to wait.
III. Of all difficult things, waiting is the most difficult. If we may only dosomething, if we may only exert ourselves, then it is so much easier, then we seem so much more content. Only be willing to wait; only fix your eyes on that cross where Christ hung, as the poor Israelite bitten by the fiery serpent looked with his whole might on the serpent of brass, and then the time shall come when you will see Him indeed.
