When was the last time you were absolutely astounded, dumbfounded, mesmerized by God?
I think if we were in a constant state of amazement and fear of God we wouldn't be able to move. Shouldn't be able to move. In comparison to a being who is so holy, everything we did or said would shrink us further. Then again, God did not create us as static beings.
The prophet Isaiah was completely ruined at a glance of God. I relate to Isaiah when he cries, "I am a man of unclean lips." (except for the man part)Jesus himself said that its not what goes into a man's mouth that defiles them, its what comes out of it. Isaiah saw his corruption when he saw the holiness of God.
This holy God is also full of grace. This truth is the reason we can move and continue speaking. Like the hot coals which touched Isaiah's lips, Christ's pain took the full punishment for us. True repentance is painful. We must be completely stripped of all the corruption and crap so God can use us to our full potential. That's hope.
In "The Holiness Of God" by R.C Sproul he writes, "Isaiah was shattered into as many pieces as any fallen egg. But God put him together again. God was able to take a shattered man and send him into the ministry. He took a sinful man and made him a prophet. He took a man with a dirty mouth and made him God's spokesman."
That amazes me.
