In the eighth year of his reign, while he was still a youth, Josiah began to seek the God of his ancestor David, and in the twelfth year he began to cleanse Judah and Jerusalem of the high places, the Asherah poles, the carved images, and the cast images.
These verses are a great reminder that we are never too young to be passionate about following God, or effective in how we live our lives.
Do we take God's Word this seriously? We have access to every single thing God wanted revealed to us. How often do we neglect even reading it, never mind following it!
Unfortunately, as we see from this passage, you cannot legislate a change of heart. The people followed God as long as it was the law of the land, and as long as their King followed God - but clearly it wasn't a heart transformation for them, as it was for Josiah. We need God to replace our heart of stone with a heart of flesh.
