"Even you guys recognize that we’re in a cursed and fallen world. That it “ought” not to be this way. I believe God designed our hearts perfectly. In fact, He’s sustaining your heart beat even as you read these words. It takes no thought on your part. No conscious effort to flex its muscle. And while you’re alive it never rests even while you sleep. Have you thanked the Lord for keeping your heart steady and working?"
That's right, it's not your brain stem that sends signals to your heart to keep it beating; it's God. Good grief.
