What does the Bible say about Isaiah's vision of God's glory?

In Isaiah 6, the prophet Isaiah sees a revelation of God's glory and majesty in the person of Christ. He describes seeing the Lord sitting upon a throne, high and lifted up, signifying Christ's sovereign dominion. This vision illustrates the holiness of God, as Isaiah is overwhelmed by the presence of the Seraphim declaring, 'Holy, holy, holy is the Lord of hosts.' The vision serves as a reminder that God's holiness demands a humble and broken heart from His servants, as they recognize their sinfulness in contrast to God's perfection.
