The first thing God had Gideon do was destroy the altar, the place of worship, the false gods, and the false teachings. If there is a false god, the teaching will not be correct. If God's people do not have the right teaching, they cannot develop in His image! It takes a true minister, speaking the truth of God for people to be prepared in the image of God. As long as a false god is before them, they will be going in the wrong direction! The prophet Ezekiel points out in Ezekiel 20 that it was idolatry and Sabbath-breaking that caused Israel to go into captivity. The same pattern of sin repeats itself throughout its history.
