Idols are false gods.
They try to take the place of God.
Idolotry is a spirit of witchcraft. So are control and manipulation which are what idols perpetuate by their presence.
God wants to clear our land again of idolotry and be our one true God. Repentance and confession are just one step away from Freedom in Christ.
His heart was devoted to the ways of the Lord ; furthermore, he removed the high places and the Asherah poles from Judah.
2 Chronicles 17:6
