But they that wait upon 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
The eagle is a creature of great strength and courage, and he lives for many years. His wingspread is six to nine feet, and he can lift himself high into the air. However, when the eagle ages, he molts and the feathers, which are so important for his passage through the air, begin to drop out. His strength goes with them.
Instinct tells the eagle that the time has come for a renewing. He seeks out a high perch, away from distractions, and he just sits. It is windy up there, and the wind carries away the feathers. Time passes. Days become weeks, and still he sits.
After a long time, the eagle’s feathers begin to grow anew, and strength again surges through him. He flexes his wings, and one day he flies high into the air. As he soars, he lets out a great scream. No doubt every creature down in the valley hears that shout of victory and trembles! They know he will be swooping down, at speeds up to one hundred miles an hour, and snatching prey.
God used the eagle as an illustration of how the Lord can renew a Christian’s strength. Life and its circumstances can bring physical, emotional, and spiritual weariness. Maybe we do not have the strength and enthusiasm for the Lord’s work that we once had. The enemy of our souls may even suggest that our time of usefulness is past.
Our focus verse is in the Bible to give us hope. As we wait upon the Lord and rest in Him, our strength will be renewed. We can remember the consecrations we once made to the Lord and refresh them. We can make new consecrations as we draw closer to the Lord in communion with Him, spending more time in prayer. God will give new zeal and courage. As we step out on the promises of God, He will give us power to defeat the enemy. Our shout of victory for God can cause the forces of Satan to tremble! There are greater vistas before us, heights to which we have not yet climbed. Let us purpose to allow God to renew our strength.
