One of the few good Kings, Josiah, was restoring the ruined Temple in Jerusalem. The workers came across, what was essentially the long lost Bible. Josiah was distraught by all that had been lost and renewed his kingdom by following the Book of the Covenant. I think we’re due for another Josiah.

  And the king stood in his place and made a covenant before the Lord, to walk after the Lord and to keep his commandments and his testimonies and his statutes, with all his heart and all his soul, to perform the words of the covenant that were written in this book.
