In 34 years of nursing in Australia, I have witnessed some amazingly inspirational outcomes when health care is supported by prayer.
One thing that has also impacted on me; those patients who have a faith, and also pray, always seem cope with, & overcome whatever it is that challenges them. Whether it be a terminal illness, or some other, less life threatening, illness. It never ceases to inspire & amaze me how those people who "believe" and pray, more often than not, have much better outcomes. Or, at least they deal with their illness in a dignified, calm & "healthy" way.
I've also been privileged to witness it personally within my own family, and through friend's. Always the same, a positive outcome, and/or, a positive dealing with the illness if terminal.
I'm also of the opinion, when nurses tend their patients in a manner which is "Christ like", both the nurse and the patient, benefit!
