Peace in Isaiah

Isaiah.  Who know what he is talking about?

Why were these 80 pages included in the Bible?  Reading the selected chapters of Isaiah in the Book of Mormon seem to go on FOREVER!  (How many people have never gotten thru them so they didn't even finish the whole BofM?)  And yet, they apparently are important enough that God wanted them recorded (painfully so as writing was not easy in those days) in at least two places.

A long time ago, there was a family in my parent's ward whose son was killed while on a church mission.  Naturally, everyone was shocked and devastated, etc.  It was particularly hard on the parents.    Here was their son doing exactly what he was suppose to be doing and yet the Lord still allowed him to be killed.  He was already sorely missed and now he was never coming back to their home.

After a few years, the mom said that she had gotten through this hard period of her life by turning to the scriptures.  She especially found peace in Isaiah.  Ever since I've heard that, I've wondered what kind of secrets Isaiah is hiding from me?
