Marshall seems to just have it all down. So, I'll toss him something and see what he does with it.
You are a pastor. You have been asked by a young couple to join them, their family, and their doctors, to explore options for a child the young couple had, prematurely, a few months back. The child has had many problems, some surgeries, and has been diagnosed with a chronic, debilitating physical condition the relief of which is necessary but normal relief will result in catastrophic physical collapse. In other words, the options are - do something, and your child dies in pain; do nothing, except ameliorative care, and your child dies comfortably. In either case, the result is the same. In the first case, the death may be postponed, perhaps by weeks or months, as different options are attempted. In the second case, it may be a few days to a few weeks.
Please, Marshall, I would like to know your feelings. Not what you would tell these people to do (although I am quite sure you would). I just want to know what you might do given this situation.
