Isaiah 6:1-8 - the call of Isaiah:
Who he was: ? - not sure, but a son is mentioned in 7:3 and he conceives a son in 8:1-3
Nature of call: HOLINESS! vision of God on throne, his robe filled the temple, seraphim calling God holy, doorposts and thresholds shook, temple filled with smoke
Isaiah's response: Woe is me, for I have seen God, and I (my lips) am unclean and live among unclean people!
God: sent a seraphim to touch Isaiah's lips with a burning coal - now your guilt is gone, your sin is atoned for - whom shall I send? Who will go for us? ("us" instead of "me" - trinity)
Isaiah: "Here am I. Send me!" (Isaiah doesn't even know what he's volunteering for yet.)
God: says with irony - go tell (your own) people, the people you live among, to repent and be healed (they won't)
Isaiah: "For how long?" No hesitation to obey.
God: until this land is utterly forsaken
in this passage, Isaiah is overcome with awe and eagerness
