What is the significance of Isaiah seeing God's glory?

Isaiah's vision in Isaiah 6 highlights the transcendence and holiness of God. When Isaiah sees the Lord sitting on the throne, high and lifted up, he recognizes his own unclean state, saying, 'Woe is me, for I am undone.' This recognition comes when one truly sees God’s glory, which is fundamentally different from human glory. The seraphim proclaim, 'Holy, holy, holy is the Lord of hosts,' emphasizing God’s separateness and moral purity. Encountering God's glory leads to an understanding of our sinfulness and need for atonement. Only through a revelation of Christ's sacrifice can iniquities be purged, illustrating that a proper view of God directly impacts one's understanding of salvation and personal worthiness.
