Idolatry

“The essence of idolatry is the entertainment of thoughts about God that are unworthy of Him.  It begins in the mind and may be present where no overt act of worship has taken place….Wrong ideas about God are not only the fountain from which the polluted waters of idolatry flow; they are themselves idolatrous.  The idolater simply imagines things about God and acts as if they were true.”  --A.W.
