"You are what you think." This is more true than most people realize. I'm against doctors and the things they have to do to treat dis-eases. So many times EGW says that our doctors are supposed to be different than the world's. Not to use drugs, treat with veg meals, fresh air, sunshine, etc. We're not any different than the world's docs, and we're having the same dis-eases as the rest of the world. I read a book once called "Your body believes everything you tell it." The title alone says everything. So many people who forget things (which everyone does sometimes) say something like "... well, my mind's starting to go already." They're conditioning themselves to be morons.
Most people work for a big hospital in the congregation that I attend. My views are not welcomed there. I walk in every Sabbath knowing that my presence is a blessing to many. Sure enough, it is. How different would things be if my attitude was negative.
There will always be someone ready to cast that first stone, but I'm not going to give them a thought in my brain. Neither should you. Focus on those who you bless by being there.
