Isaiah 40:29-31:
He giveth power to the faint; and to them that have no might he increaseth strength.
Even the youths shall faint and be weary, and the young men shall utterly fall;
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.
Notes on Isaiah 40:29-31:
“Waiting on the Lord” does not mean that you have to wait for God to get around to feeling like doing something for you in His sovereign will. You are looking expectantly toward Him, not sitting passively waiting for God to do everything for you.
This verse is an implicit health promise for those who fellowship with God. You can’t run and not faint if you have a splitting headache and your lungs are full of junk. You can’t walk and not faint if you have a bad heart. If you have trouble with anemia or other forms of general weakness, spend time pondering this passage. God gives power to the faint!
