Among the sins to which the human heart is prone, hardly any other is more hateful to God than idolatry, for idolatry is at bottom a libel on His character. The idolatrous heart assumes that God is other than He is – in itself a monstrous sin – and substitutes for the true God one made after its own likeness. Always this God will conform to the image of the one who created it and will be base or pure, cruel or kind, according to the moral state of the mind from which it emerges.
