When you hear the word "idolatry," it likely brings up images in your mind of humans bowing down before statues of wood and stone.
I've never been tempted to bow my knee to an idol, but I have been tempted to put my trust in people and things other than God.
These idols have taken on different forms in the 21st century. The idols we worship are almost never bad things. We find ourselves more tempted to worship good things.
Any time we worship created things rather than the Creator, we're engaging in idol worship. Any time we turn good things into our highest priority, we're giving our worship to idols.
