Idolatry

In making the Golden Calf, Israel violated one of God's clearest boundaries. Only Moses' intervention prevented their immediate destruction. The human impulses that led Israel to worship idols have not gone away; they are still very much active. The vehicle has changed but the underlying urge to get a "better deal" than God says is proper has not changed. Going to an illicit spiritual relationship may provide short term satisfaction, but the end is misery and death.
