Answer'Idols' is a derogatory term used by one religion about the holy images of another religion. To a Christian, an image of Jesus is not an idol, but images of the gods of other religions are 'idols'. So, the concept of false idols relies on knowing which religion is right for you, and only worshipping the God or gods of that religion. And the safest way to avoid worshipping false idols is to not worship any god at all - after all many say that there really is no God.
