Have you not known? Have you not heard? The Lord is the everlasting God, the Creator of the ends of the earth. He does not faint or grow weary; his understanding is unsearchable. He gives power to the faint, and to him who has no might he increases strength. Even youths shall faint and be weary, and young men shall fall exhausted; but they who wait for the Lord shall renew their strength; they shall mount up with wings like eagles; they shall run and not be weary; they shall walk and not faint.
Interestingly that verse says, “those that wait for the Lord”, I am sure whole books could be written about what it means to wait for Him. In my simple words, my explanation is not meant as theology, just my experience. I am completely poured out, there is nothing left in me, so I wait on God in total dependence, and He meets me in this. Oh I may not feel like I am soaring like an eagle all of the time or even some of the time, but I have had glimpses of it. I feel that I am more than just surviving this. I am content to wait for Him, His timing is not the same as mine, but it is sufficient… In this I am the one that has no might, yet by God’s grace I walk in strength. (and to him who has no might he increases strength)
