" When Scripture says, "As a man thinks, so is he," it is raw truth. How we approach life and react to its vagaries determines the bulk of our character. How we love is locked into how we think about it. What angers us is triggered by how we think. It is between our ears that we decide how easily offended we will be. When it comes to harsh words from others, whether my skin absorbs like cotton or deflects like Teflon is a decision I make. All of that happens in a three-pound organ five-and-a-half inches across called my brain. In a very real sense, my world begins and ends between my ears. I don't have to be brain-dead to be brain-defeated. "
