The book of Revelation (a badly misunderstood work not about the end of the world) is addressed to seven churches. The last comes in for special disdain from the writer for being "neither cold nor hot," for being "lukewarm." That is precisely the status of the Israelites in this reading, worshiping the LORD or YHWH but also worshiping Baal. The prophet asks them, "How long will you go limping with two different opinions? If YHWH is God, follow him; but if Baal, then follow him." It's a question we do well to ask ourselves, though our Baals are usually called by other names.
