Again from ‘Whole Bible Christianity’

Another name for sin is idolatry. In modern times, we think of it only as bowing down to a statue or other image. This is part of it, but there is much more to idolatry than statues. Read Jeremiah 3:1-10.

Idolatry is ‘cheating’ on God. We cheat Him when we give Him less than whole-hearted obedience. In public, we might claim to be loyal spouses and appear to do what God says. But when we ignore His Word it’s just like cheating on a spouse. Any thought or action that doesn’t match His Word is idolatry. Or adultery.

We might comfort ourselves that we are not idolaters because we don’t have a statue in the living room (let’s overlook the crucifix, Christmas tree, Easter eggs and bunnies for now). But idolatry is not limited to actual images. If we reject His ways and do our own, it is idolatry. Paul says that covetousness is idolatry (Ephesians 5:5). God says the Chaldeans worship their own might, and Jesus says that Mammon is a god.

11 Then they sweep by like the wind and go on, guilty men, whose own might is their god!” (Habakkuk 1:11 ESV)

13 No servant can serve two masters, for either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve God and money.” (Luke 16:13 ESV)

The statue in the center of disobedience is the self-image. A 3-D statue is really self-will personified. Idolatry comes from inside, from the heart. The statue just gives it a physical shape. Adam and Eve were booted out of paradise, not because they bowed to an image, but because they bowed to self-will and knowledge. Obedience is the same as worship. Their obedience to their own understanding was just the same as worshiping a statue of themselves.
