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.
“This God-given power is experienced only by those who will wait upon the Lord. Left to themselves, old and young alike will find human might so frail and inadequate, “but those who wait on the LORD shall renew their strength.” Those who place their hope in God are strengthened by the Lord Himself. They are enabled by God to live above their circumstances, looking down on life from heaven’s perspective. “They shall mount up with wings like eagles.” When it is time to press energetically ahead, they can do so without becoming exhausted. “They shall run and not be weary.” When it is more appropriate to plod along methodically and persistently, they do not collapse. “They shall walk and not faint.” All of this results from the power of God working within those who wait upon Him.”
