See this is where you have not thought it out...The feeding tube is needed to FEED HER! Do you propose that people who need oxygen be taken off of if they need it to help them breathe, I know many able people who need it!
Who's time are we talking about, hers or God's? There are many out there that have to have the same treatment that have less problems...do you propose we starve them just because they need a feeding tube?
What makes you think God doesn't want her to be fed by a feeding tube? Is it wrong in your eyes for God to want to keep her alive this way for even 15 more years...?
Are you trying to tell God what to do and how to act?
BRAVO!! Some people can't see the forest for the trees.
