28 Hast thou not known? hast thou not heard, that the everlasting God, the Lord, the Creator of the ends of the earth, fainteth not, neither is weary? there is no searching of his understanding.
29 He giveth power to the faint; and to them that have no might he increaseth strength.
30 Even the youths shall faint and be weary, and the young men shall utterly fall:
31 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.
We should be so thankful for these verses. As we read them we should gain strength just knowing our all powerful and everlasting God never goes to sleep, he never naps, and he never takes his eyes and ears off his flock. He never grows weak or tired. He has all power and will keep demonstrating his strength and power throughout eternity. We may need a nap but Jehovah never does.
Not only will He always remain full of strength but he promises to share and supply his strength with us when we need it - and we will need it. He says even the young and strong will become weary and weak at times. (V30)
We need to remember the key to getting the supply of strength we need: WAITING on Jehovah. Like our prayer requests God answers when the timing is best and He knows best. We must trust him by faith that he will show up just in time with exactly all we need. In verse 31 he promises strength, soaring, and stamina.
He will renew our strength. He gave it to us and he will re supply. We shall have strength enough to soar like eagles. Watch an eagle soar and it seems effortless. He then says the faithful waiter shall run and walk in His wonderful strength without weariness.
