“While he was yet a boy, he began to seek the God of David his father …” (v3). King Josiah had a mixed heritage; his father was corrupt, and his grandfather had done terrible things and then repented. Josiah’s journey to know the Lord, therefore, was a process. He recognized what was evil and uprooted it (altars to idols, v3-7), but he didn’t know what God really desired for Israel until the workmen repairing the Temple found “the book of the Law” (v15-21). Then Josiah realized how far Israel had fallen.
Seeking God, like Josiah, is the just beginning. The more we understand God’s ways, the more we are able to commit “heart and soul” (v37) to follow Him
