After the misery of reading all about Israel's decline into spiritual depravity, I loved reading about Hezekiah's passion for God.
One part I found interesting was the smashing of the bronze snake Moses had made. Originally this bronze snake symbolized God's presence and power, and was a reminder to the people of His mercy and forgiveness. Unfortunately, it had become an object of worship instead of a reminder of whom to worship, and Hezekiah rightly had it destroyed. Even something that was not made to be an idol can become an idol by the way people use them. We have to be careful not to do the same thing - worship creation instead of the Creator, worship money instead of stewarding it for the kingdom, etc.
Our NT passage was a reminder that the heart of man is inherently sinful. We are not intrinsically good. We need a spiritual heart transplant. Thankfully, that's exactly what salvation is. God gives us a new heart, and puts new passions within us. This new heart will manifest itself in our actions, of course, but we need to always remember that everything flows from the heart. We also need to remember to nurture our new heart with spiritual food and not deprive it by filling our minds with trash.
