This book has dragged on forever. The folks that compiled the KJV left out a lot of stuff. Why didn't they cut Isaiah down to 20-30 chapters?
We do get some really good writing from Isaiah at the end and he asks a really good question;
'Hey God! Where did you go? Why don't you hang out with us like you did with Abraham and Moses?'
He asks these questions but he already knows the reason. Israel is a collective bunch of screw-ups who can't/won't follow God's rules. Pretty simple.
God has a good answer for him;
'I watch you continually disappointing me and I know you'll always be this way but I won't destroy you completely. Some of you will obey and I'll be nice to you.'
He seems to indicate that he'll start again from scratch;
65:17 For, behold, I create new heavens and a new earth: and the former shall not be remembered, nor come into mind.
Chapter 66 is how ALL the books of the bible should end!!! Fire! Death! Redemption! Every word is gold. We get a concise explanation of what God plans to do.
Isaiah may be long-winded but he knew how to finish with a bang.
