What is Elijah doing in 1Kings? He's teaching the Israelites the Uniqueness of GOD. Here in 1Kings 21 we find Ahab abandoing himself to a differnt 'god'. False worship leads to false desire (or at least to the desire for the wrong things) False desire leads to false advice on how to obtain those things. What Ahab plans and does is not pretty, but the real God calls him to account, and even here God shows Himself merciful.
