It's the result of sin, of living in a fallen world and inheriting a fallen nature. This has profound implications for us as Christian doctors. We recognise that death is inevitable and that we are ultimately powerless to stop it. Instead we'll recognise when it's inevitable and be honest about our own limitations. We won't speak of it as a glorious release either.
Medicine is much more than death prevention.
It's about relieving symptoms, forestalling complications and above all consoling, advising and caring for patients. For some it's the desire to get rich or to exercise power over disease or other human beings. Or perhaps to win the approval of society, particularly of patients and colleagues. I think that most non-Christian doctors genuinely want to make a difference in the lives of others. The issue is why people want to make a difference.
