The Bible speaks much of idol worship. I suspect that in today's culture, most of us breeze right through those passages. We think because we don't have a golden calf in the yard or aren't bowing to a statue, that these Scriptures don't really apply to us. But idol worship begins whenever we focus more of our attention on anything that is created - than we do on the creator Himself.
So anytime my focus on anything created is greater than my focus on the creator, I'm guilty of idolatry!
