Like grapes in the wilderness, I found Israel. Like the first fruit on the fig tree in its first season, I saw your fathers. But they came to Baal-peor and consecrated themselves to the thing of shame, and became detestable like the thing they loved. (Hos 9:10 ESV)
The great danger of all our worship is that it will slowly and surely take hold of our hearts until we become like the very thing we worship. Not literally but in very nature of its moral quality. Think of Smeagol and how he becomes like Gollum in the movie Lord of the Rings. His desire for the ring overtook all moral sensibilities and drove him to his death. You can see the transition as story progresses.
