II Kings 22:13 Go ye, inquire of the LORD for me, and for the people, and for all Judah, concerning the words of this book that is found: for great is the wrath of the LORD that is kindled against us, because our fathers have not hearkened unto the words of this book, to do according unto all that which is written concerning us.
Josiah hears the Word of the Lord and is shocked. He realizes that was he is hearing has not been fulfilled by his people. He realizes that these are more than words and that God has commanded His people to do certain things. He is concerned enough to try and right the wrongs. His heart is broken. He begins to do all that he can do to fix the wrongs that have been done.
I think that the lesson for us here is to hear what He actually says in His Word to us. Then we must question ourselves; Are we doing what He teaches us or tells us to do? Have we concerned ourselves with the spread of the gospel around the world as He commands us? Do we take to heart what He says? Do we truly believe that there is a literal, physical, Hell?
Have we turned a book that commands us to serve into a religion of a God that is to serve us? I wonder if our God might be angry today with us because neither our fathers nor we have hearkened unto the words of this book?
