Yes, the whole Bible is amazing, but I've never read Isaiah before, so I'm just focussing on it. And why not? Chapters 25-26 are full of things like salvation by faith, God's grace, resurrection of the dead, the proud made humble, the fact that what we accomplish is done for us by God, God planning things aaaages ago. No wonder its quoted in the NT so much. Also, comparing 25:8 with 1 Corinthian 15:54 and Rev 21:4 - they're the same. I didn't know Rev 21:4 was actually quoting Isaiah!
And that is what I've been thinking about.
