Isaiah 40:28 meaning

God is all-powerful, all-knowing, and never grows tired, offering unending confidence and strength to all who trust in Him.

“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.” (v.28) In this verse, Isaiah—an 8th-century BC prophet—reminds his readers of God’s eternal nature and power. The rhetorical questions “Do you not know?” and “Have you not heard?” urge the people of Judah, and all who read this text, to recall what they have been taught about their Creator. Isaiah highlights that God never becomes weary like humans do. He is the “Everlasting God,” the One who exists outside of time itself and forms each corner of the earth.

The prophet underscores the divine attribute of infinite wisdom by proclaiming that God’s “understanding is inscrutable.” This means His knowledge cannot be fully measured or comprehended by finite minds. In a world filled with difficulties—where people constantly grow tired, stressed, or frustrated—the promise of God’s tirelessness and boundless understanding brings comfort and security. Believers can lean on Him for strength, confident that He is able to sustain them through every challenge.

The reference to Him as “the Creator of the ends of the earth” also stresses His sovereignty over all creation. Since God is the Maker of everything and everyone, there is no place where His authority and care do not extend. This passage provides both reassurance and motivation for those who seek hope, encouraging them to turn to the One who never grows faint.
