"An idol is anything more important to you than God, anything that absorbs your heart and imagination more than God, anything you seek to give you what only God can give."
Who do you idolize? There are many idols in the world today... They may be other people, fame, fortune, yourself... God hates idolatry more than anything but loves the humble. This is why when his son came the first time it was as a servant but the next time it will be as a warrior and King!
