Idols are man-made, not God made, that we give power to that we should be giving to the one true God.
I made an idol of the first new car we bought, I gave it the power to make me happy and complete. Then I drove it to the river to go swimming and that thing got stuck in the mud up to the hubcaps. I had to hire a wrecker to get it out and not ever let my husband know. That car lost its place as an idol!
