God had Moses to make a brazen serpent to provide a healing to those that looked upon it. Instead of solely glorifying God, the Israelites began to burn incense to the brass serpent as part of their worship. Hezekiah realized their error: they were worshipping the means instead of the Master. Hezekiah broke the serpent into pieces. 
Circumstances, opportunities, health, careers, positions, etc. aren’t where our security should derive from. They aren’t deserving of our worshipful devotion. Instead our hope and trust should rest in Jesus alone. He is looking out for us, working all things to our good.
