The Lord Shall renew their strength.
Isaiah 40:31 'Key Verse'
"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."
Note: To wait on the Lord is to trust Him fully with our lives. It involves looking to Him as our source of help and grace in time of need. Those who wait upon the Lord are promised of three things: (1) the strength of God to revive them in the midst of exhaustion and weakness, of suffering and trial; (2) the ability to rise above their difficulties as an eagle that soars into the sky; and (3) the ability to run spiritually without tiring and to walk steadily forward without fainting at God's delays. God promises that if His people will patiently trust Him, he will provide whatever is needed to sustain (support) them constantly.
Dorothy: It would be good to read New Century Version from Isaiah 40:12-31 because Isaiah, the prophet gives a clear picture that God is Supreme. Even God challenged Israel if they can compare God to anyone and is anyone equal to Him? Look at the nature that He alone has created and that idols do not created anything at all.
I will start with Isaiah 40:28-31: "Surely you know. Surely you have heard. The Lord is the God who lives forever, who created all the world. He does not become tired or need to rest. No one can understand how great His wisdom is. v29 He gives strength to those who are tired and more power to those who are weak. v30 Even children become tired and need to rest, and young people trip and fall. v.31 But the people who trust the Lord will become strong again. They will rise up as an eagle in the sky; they will run and not need rest; they will walk and not become tired."
How is the eagle "renewed" each year?
Each year the eagle replaces its feather over a period of several months. However, not like the other birds who becomes 'naked' after losing all their feathers. The naked birds cannot fly until they get their feathers grown back. But eagle is different. While the old feathers fall out or moult, the new feathers comes in at the same time. So the eagle is able to continue hunting for food throughout the entire renewal process. The eagle can still fly while the feathers are being replaced. The eagle has been known to live through to 100 years because of the renewal of the strength. This is why God compares us to eagle. We, like the eagle, need "new feathers" or "new strength" to become strong like an eagle. There is a favorite song that has been a blessing to many of us. May the Lord bless you.
Song: They That Wait Upon The Lord.
They that wait upon the Lord shall renew their strength,
they shall mount up with the wings as an eagle;
they shall run and not be weary, they walk and not faint.
Teach me Lord, teach me Lord to wait....
