What does God think about your “god”?

If you create an imaginary god in your mind, let’s call him, her or it, Harry, what do you think the one, true and living God thinks about the imaginary Harry? The Bible says He hates idolatry. Or, if the “jesus” you call on speaks and acts differently than Jesus of Nazareth, and has lesser standards than Him, it’s the same, it’s an idol, not Jesus.
