Isaiah 40: 25 To whom will you compare me? Or who is my equal? says the Holy One.
God knows that as mortals we have questions about his deity and right to rule. Some set out to challenge God, but Isaiah 40 sets out to enlighten and bring comfort to God’s people – those who are seeking after God with their whole heart. A contrast is drawn between the frailties of man and the awesomeness of God. “Surely the people are grass. The grass withers and the flowers fall, but the word of our God stands forever.” “Here is your God!” “See, the Sovereign Lord comes with power and his arm rules for him.” The so-called might of nations is put into perspective: “Before him all nations are as nothing; they are regarded by him as worthless and less than nothing.” In contrast: “He sits enthroned above the circle of the earth and its people are like grasshoppers. He stretches out the heavens like a canopy and spreads them out like a tent to live in. He brings princes to naught and reduces the rulers of this world to nothing.”
God presents himself as the Holy One, the Creator. On that basis alone you have to ask yourself, “To whom can I compare God?” You are invited to lift your eyes and look to the heavens and ask: “Who created all these?” The answer is provided for you, “He who brings out the starry host one by one, and calls them by name. Because of his great power and mighty strength, not one of them is missing.”
Like Israel, you as a believer have no reason to complain that your way is hidden from the Lord or become discouraged thinking that your cause is disregarded by your God. “Do you not know? Have you not heard? The Lord is the everlasting God, the Creator of the ends of the earth. He will not grow tired or weary, and his understanding no one can fathom.” Recognizing God’s authority over everyone and everything means you can draw on his strength when you feel weak and powerless. It is a promise: “Those who hope in the Lord will renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint.”
