But God in His great mercy gave me the "fresh strength" I needed, just as these verses say--and what a blessing to know that no matter how exhausted I am--whether I have the strength to walk across the room or not--HE NEVER GETS TIRED OUT. And, because He's God and is control of it all, that brings me great comfort. I hope it does you, too.
Thank you, Lord, for Your strength. All glory and honor be to You, Almighty God!
