“Those who wait on the LORD shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.” - Isaiah 40:31
Our waiting on God will depend greatly on our faith of what He is. In our text, we have the close of a passage in which God reveals Himself as the everlasting and almighty One. It is as that revelation enters into our soul that the waiting will become the spontaneous expression of what we know Him to be - a God altogether most worthy to be waited on.
Listen to the words, "Why do you say, O Jacob . . . My way is hid from the LORD . . .? Have you not known? have you not heard, that the everlasting God, the LORD, the Creator of the ends of the earth, faints not, neither is weary?" (Isa. 40:27-28). So far from it: "He gives power to the faint; and to those who have no might he increases strength, even the youths shall faint . . . and the young men shall utterly fall." (vs. 29-30). And consider that "the glory of young men is their strength." (Prov. 20:29). All that is deemed strong with man shall come to nothing.
"But those who wait on the LORD," on the Everlasting One, who does not faint, and is not weary, they "shall renew their strength; they shall mount up with wings as eagles; they shall run, and" – listen now, they will be strong with the strength of God, and, even as He, they will "not be weary; and they shall walk, and" even as He, they will "not faint."
Yes, "they shall mount up with wings as eagles." You know what eagles' wings mean. The eagle is the king of birds; it soars the highest into the heavens. Believers are to live a heavenly life, in the very presence and love and joy of God. They are to live where God lives; they need God's strength to rise there. It will be given to those who wait on Him. You know how the eagles' wings are obtained. Only in one way - by the eagle birth. You are born of God. You have the eagles' wings. You may not have known it; you may not have used them; but God can and will teach you how to use them.
You know how the eagles are taught the use of their wings. See yonder cliff rising a thousand feet out of the sea. See high up a ledge on the rock, where there is an eagle's nest with its treasure of two young eaglets. See the mother bird come and stir up her nest, and with her beak push the timid birds over the precipice. See how they flutter and fall and sink toward the depth. See now how she "flutters over her young, spreads abroad her wings, takes them, bears them on her wings" (Deut. 32:11), and so, as they ride on her wings, brings them to a place of safety. And so, she does this once and again, each time casting them out over the precipice, and then again taking and carrying them.
"So the LORD alone led him" (v. 12). Yes, the instinct of that eagle mother was God's gift, a single ray of that love in which the Almighty trains His people to mount as on eagles' wings.
He stirs up your nest. He disappoints your hopes. He brings down your confidence. He makes you fear and tremble, as all your strength fails, and you feel utterly weary and helpless. And all the while He is spreading His strong wings for you to rest your weakness on and offering His everlasting Creator strength to work in you. And all He asks is that you sink down in your weariness and wait on Him. Allow Him in His Jehovah strength to carry you as you ride on the wings of His omnipotence.
Dear child of God, I pray you, lift up your eyes, and behold your God! Listen to Him who says that He "faints not, neither is weary" (Isa. 40:28), who promises that you too will not faint or be weary, who asks nothing but this one thing, that you should wait on Him. And, let your answer be with such a God, so mighty, so faithful, so tender; “My soul, wait only on God!”
