God brings a lawsuit against his people. At the heart of it is idolatry, but the idolatry expresses itself in greed and theft, a breaking of the 8th commandment. God’s call to repent in Micah 6 involves two things. Paul summarizes them well in Ephesians 4:28: “He who has been stealing must steal no longer, but must work, doing something useful with his own hands, that he may have something to share with those in need.” That gets to the heart of the 8th commandment: it is about stealing, but also about working for one’s neighbor’s good.
