Judges 17-18

“Now I know that the LORD will prosper me, because I have a Levite as priest" (v13).  In this time, “everyone did what was right in their own eyes” (17:6), and the worship of God was mixed up with idol worship (syncretism).  Instead of worshipping at the official tabernacle, Micah had a household shrine and idols, and he thought having his own Levite priest would give him supernatural power (v5). Instead, a group of Danites stole his priest and his idols (ch 18), symbolizing the spiritual chaos of the land. 

“Inquire of God, please … “ (18:5).  Thinking we can manipulate God to get what we want is magic, not Christianity.  God calls us seek His glory,  not our own.
