"Do you not know? Have you not heard?
The Everlasting God, the LORD, the Creator of the ends of the earth
Does not become weary or tired.
His understanding is inscrutable."
Isaiah 40:28
God is not like we are. He never gets weary or tired. He doesn't need caffeine or an afternoon nap to get Him through the day. In fact, He doesn't sleep at all (Psalm 12:4). God's understanding, His intelligence, is perfect. He can't lose intelligence, nor can He gain more intelligence. His intelligence was, is and always will be perfect and unfathomable. Now consider this, why would we trudge through this life in our own pitiful strength, when we can soar like eagles (Isaiah 40:31) in the strength of the One who understands far more about our situation than we do? Whatever trial or challenge you may be facing today that has you worn out, lay it at the Savior's feet. Just put it down right there and pray, "Lord, I'm tired. I need Your unending strength to get me through this. Come in all Your infinite understanding and help me, please." Ask Him in your weakness and He will answer You in His strength.
