"What is an idol? It 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… An idol is whatever you look at and say, in your heart of hearts, 'If I have that, then I’ll feel my life has meaning, then I‘ll know I have value, then I’ll feel significant and secure.' There are many ways to describe that kind of relationship to something, but perhaps the best one is worship."
David Foster Wallace:
"In the day-to-day trenches of adult life, there is actually no such thing as atheism. There is no such thing as not worshipping. Everybody worships. The only choice we get is what to worship. And an outstanding reason for choosing some sort of God or spiritual-type thing to worship…is that pretty much anything else you worship will eat you alive. If you worship money and things— if they are where you tap real meaning in life— then you will never feel you have enough…. Worship your own body and beauty and sexual allure and you will always feel ugly, and when time and age start showing, you will die a million deaths before they finally plant you…. Worship power—you will end up feeling weak and afraid, and you will need ever more power over others to keep the fear at bay. Worship your intellect, being seen as smart— you will end up feeling stupid, a fraud, always on the verge of being found out."
