Ahab was haunted by his own greed. Ahab was haunted by his own disobedience of God. Ahab was haunted by his own guilt and shame. In a way, Ahab was haunted by Elijah... because Ahab couldn't seem to get away from Elijah. Elijah was a reminder of the drought. Elijah was a reminder of the showdown on Mt Carmel. Elijah was a reminder of the power of God. This episode reminds us that whatever we sow, that we will also reap . It is also a reminder that since we cannot cover up our sin, we should confess it and forsake it.
