'The Bible used the picture of idolatry as a way of describing anything that takes the place of the true God in our lives. Not depictions of the Greek goddess of love Aphrodite, but mental images of naked bodies. Not literal temples where we go to worship real statues, but inner urges for more and more. Not stone altars to sacrifice on, but bragging about the money in the bank and the turnover of the market stall. It's all idolatry: putting something else in God's place.'
Julian Hardyman, Idols: God's Battle for Our Hearts, p.15.
