Think

Sin begins in the mind--the thoughts. "Casting down imaginations" "Taking every thought captive to obedience." "As a man thinks in his heart, so is he."

And you don't think it matters what you feed your mind?

"Be not conformed . . . be transformed by the continual renewing of your mind"

"Here is a last piece of advice. If you believe in goodness and if you value the approval of God, fix your minds on whatever is true and honorable and just and pure and lovely and praiseworthy."

"Set your mind on things above where Christ sits at the right hand of the Father."

Cast down. Take captive. Renew. Fix. Set. How healthy is your mind? How holy--Christ-like--is your life?

Same question.
