Contrary to what you will hear in many counseling circles today purporting to be Christian, the way to help people solve their problems does not lie in discovering some idol(s) in their hearts. Listen to what Scripture says about hearts:
You alone know the human heart (2 Chronicles 6:30)
Since that is true, it is foolishness—not to say presumption—to claim to be able by some technique or other to be able to know what Scripture teaches that only God can know!
Why, then, is this idea so prevalent among Christians who counsel? A good selling job has been done it seems.
I warn you against adopting this approach in which such silly things as calling “over-sleeping” an idol are “discovered.” True, a person may (along with other matters) have a sleeping problem, but that it is an idol which he has manufactured in his heart—sounds strange to me, How about you?
