No reasonable hope? Please, that is a load of BS. I have seen a young man, who by all medical definitions, had no reasonable hope. Because of the work of nurses, therapists, and a strong family love and dedication, he has proven that "diagnosis" of "no reasonable hope" to be wrong. Let me add that when there is no "reasonable" hope we also have hope in our Saviour's healing power. There are some of us who do not place all of our hopes on man's ability. While recognizing medical science for the blessing that it is, there is a Greater Physician who says it is not the final authority.
The human brain has been and will remain a mysterious organ. Divinely created it cannot be decoded by man and machines. It holds potential not yet unlocked. I ask you, when Terri smiles, when she cries, when she responds to stimuli, what is that? Is it a coincidental reflexive response? Sorry, I don't buy that. It is an appeasement. It is easier to say that it is reflexive rather than to say, "I don't know. I don't understand everything there is to understand about the human brain. It is too complex for my finite mind".
When you, or anyone else, finds the key that unlocks the mysteries to the human brain and discovers ALL that there is to know about it, get back with me. Upon your proof that you have ALL of the answers, only then will I accept your opinion of no reasonable hope.
