The problem here is that this poster miraculously intervenes at the right time, every time. I believe in God, and I talk about him when appropriate with my patients. I don't post every "win" with patients, and to be honest, I don't post any "win" at all. Because what occurs between myself, a patient, and faith happens to be between those three and no one else. Fun fact: it's usually not miraculous.
It's when I talk to the patient who has just decided hospice is the place for them and they are dying. It's when the patient has a terminal cancer that they understand is the end for them, and nothing can prolong their life. It's the patient on hospital hospice who decides they would like to be saved.
I don't doubt that this can happen maybe once in a nurse's career, but for myself, it's sacred, and it's small things. This sort of thing does not happen every day. It doesn't even happen every year. It's something that is amazing to experience, but it is not common. You cannot come into this with the idea that God will give you the supernatural ability to become the best nurse ever just by being a Christian.
We, as Christians, are fallible, imperfect, and above everything else, sinners. There is no special powers or abilities that we have, although we must believe that God is capable of such a feat. However, those imbibed with such power would not brag in such a manner. Be upfront. Talk about God in the proper context, but don't give those who believe that they can do so much more... without posting the failures. This poster is human, and there are mistakes that he/she has made. We don't get to see that. It's like facebook, this poster only puts forward his/her best foot. It's not realistic.
