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.

— Isaiah 40:28

People get exhausted, but the Lord never grows tired. People are born and die, but God is immortal and everlasting. People are creatures, but God is their Creator. People have some knowledge, but God's understanding is beyond our comprehension. People dare to question God, but our arguments are unreasonable.In our text for today the prophet Isaiah points out the eternal nature of God. He is before and beyond time. Time is in his hands. God is the one who was, who is, and who is to come. Further, Isaiah emphasizes the sovereignty of God. He is the Lord. He governs the universe, the nations, the church, and our lives.God is the Creator of the ends of the earth, the master of the whole universe. Matter is not eternal. The world did not arise by itself. Our world and its solar system and all the stars and galaxies we can see when we look into space—all of it has been created by God.Isaiah also emphasizes that God is tireless. He is still at work today. He does not need to regain strength. He gives strength to the powerless.In addition, God’s understanding is unsearchable. His wisdom and knowledge are unfathomable. What a great, amazing God we serve! We can trust and obey him as we live each day in his care.

Eternal God, tireless and wise, strengthen us in our weakness. Help us to trust in your sovereignty, to rest in your care, and to obey your will. Amen.
