[A] misunderstanding of sin is to say that it’s just a matter of negative thinking.… Get rid of your old wineskins! Think bigger! God wants to show you his incredible favor, if you’ll just get rid of all those negative mind-sets that hold you back!
Now that’s a compelling message to self-reliant people who want to believe they can take care of their sin all by themselves. That’s probably why men who proclaim that message have managed to build some of the largest churches in the world. The formula is pretty easy, really. Just tell people that their sin is no deeper than negative thinking and that it’s holding them back from health, wealth, and happiness. Then tell them that if they’ll just think more positively about themselves (with God’s help, of course), they’ll be rid of their sin and get rich, to boot. Bingo! Instant megachurch!
Sometimes the promised goal is money, sometimes health, sometimes something else entirely. But however you spin it, to say that Jesus Christ died to save us from negative thoughts about ourselves is reprehensibly unbiblical. In fact, the Bible teaches that a big part of our problem is that we think too highly of ourselves, not too lowly. Stop and think about it for a moment. How did the Serpent tempt Adam and Eve? He told them they were thinking too negatively about themselves. He told them they needed to think more positively, to extend their grasp, to reach toward their full potential, to be like God! In a word, he told them to think bigger.
Now how’d that work out for them?
