Sometimes we just need a dose of reality. We have zero strength except that which God has given. And if our strength is solely of our physical, emotional selves, then it cannot take us very far. God alone gives life and strength.
"Who has measured the waters in the hollow of His hand, measured heaven with a span and calculated the dust of the earth in a measure?" (40:12)
Yet we can vainly think we are something apart from Him.
"With whom did He take counsel, and who instructed Him, and taught Him in the path of justice? Who taught Him knowledge, and showed Him the way of understanding?" (40:14)
He alone is God. He alone creates, sustains, and justifies. So what are we to do? We "lift up (our) eyes on high, and see who has created these things (the heavens, the earth, and all that is within), Who brings out their host by number; He calls them by name, by the greatness of His might and the strength of His power; not one is missing." (40:26)
This is the God reigning sovereign on high. Do you trust in Him? The amazing thing is that He wants you and I to fully rest in His majestic hands. "Fear not, for I am with you; Be not dismayed, for I am your God. I will strengthen you, yes, I will help you, I will uphold you with My righteous right hand." (41:10)
So let's get something straight: we are hopelessly weak apart from Him--but withering grass. He alone is God; we--thankfully--are not! May we turn our eyes to Him and let Him "make the wilderness a pool of water, and the dry land springs of water." (41:18b)
