04-Application of the Passage

What has all this to do with us? This is where we came in.
As I said at the start:
Why spend time writing a book on the solemn preaching of
a prophet who addressed Israel and Judah over 2500 years
ago – preaching that was largely rejected by his own people
at the time? What‟s the point? What can Isaiah have to say
to us today? If his own people in his own generation didn‟t
listen to him, why should we?
Are these real questions? – asked by a believer, I mean.
