It's really amazing how dim humanity's eyesight is. From the days of Adam until now, we continually do things our way. In this passage, where the law compares the worship of pagans against that of Israel, God is sure to make it clear that, even in our best attempts, we still don't get it right.

Is God displeased at our own attempts to worship Him? Is there really only one way? Where has he established that? The only way I see is in Temple worship, and Jesus put that away when He said we will worship "In Spirit and Truth" to the Samaritan woman at the well.
