The God of Isaiah 6 blows away the comfortable, manageable God we’ve fashioned for ourselves. It reminds us of how small we are and how great He is.
In Isaiah 6, Isaiah sees God sitting on a throne. Not pacing. Sitting. He is in control. He knows it. No one is worried. What problem would seem too large for the One sitting on the throne?
Maybe the reason the Church has lost its moral vision is because it has lost its high and exalted view of God. We have embraced the comfort of His nearness at the expense of His transcendence.
The Seraphim chant “holy, holy, holy,” never-ceasing. When the truth is significant there is great power in repetition, especially if the subject is an attribute of God.
