I would hate to be a child in the hands of a family who refuses blood. I still don't understand all the refusal of blood. I mean look at it this way, if you are going to die, would you rather be given blood and live a day or two or even years or deny blood and not live at all. People do far worse things then receive blood. My thought is if God did not want us to use blood to live he would have stated so in the commandments and made it very clear to do so.
Here's a little story, I had a friend who lost his child, they just turned 18 years old. Her parents donated her organs and her loss saved 5 other people! Her blood was also used on one of the people who needed the transplant.
I also know that If I am in need of blood, I am going to take it. I'm not going to sit there and let myself die. Id rather contract an illness that can be likely taken care of with modern medicine then just let myself go.
Those cards that JW are forced to carry at all times is stupid, that's putting their life in someone elses hands and they do not have a say what so ever. That is almost like a binding contract.
I wouldn't want that.
