What, so if your husband is in a state where his brain is liquid and there is no chance whatever of survival, you will insist on keeping him "alive"? Even if his parents want him to be at rest, and to pull the plug? I used brackets for "alive", simply cuz I believe that if you are in a state where it's only machines that are keeping you going, that is not life. That is existance, and condemning a person to that is cruelty in the extreme.
And yes, I am thinking of this case: Terri Schiavo case - Wikipedia, the free encyclopedia
If you're bringing God into it, then surely all medical intervention is going against God's wishes? I don't claim to be an expert, but the given story is that if He wants you to die, then you die. You can't take one side, ie saying you want your husband kept alive by machinery, and not the other, saying you want a miracle. Turn the machines off; if there is that miracle, it will happen then.
