When you go a week without seeing a human face, that does something to you.
My 4-year-old son prays every night for his best friend who is the same age - our next door neighbor in Liberia, a little Liberian boy: 'Dear God, please don't let him get Ebola.' I'm proud of him for thinking about his friend and praying for him but that's not a prayer that a 4-year-old should have to consider.
There are a lot of health care providers in this country who have a very deep sense of service and compassion for the suffering of others, who are motivated to go to West Africa despite the risks of infection and death. And doctors and nurses face those risks every day regardless of their setting.
I wasn't afraid of treating Ebola patients in the isolation unit. That was the safest job. But seeing patients in the clinic, seeing patients in the emergency room, being in the community - those things gave me pause.
God blessed me with a peace that surpasses understanding.
I know that some consider it controversial for me to claim that God saved my life when I had received an experimental drug and some of the greatest medical care available in the world. I can see how these two realities appear to contradict each other.
Through the care of the Samaritan's Purse and SIM missionary team in Liberia, the use of an experimental drug, and the expertise and resources of the health care team at Emory University Hospital, God saved my life - a direct answer to thousands and thousands of prayers.
As the Ebola virus continued to consume my patients, I witnessed the horror this disease visits upon its victims, the intense pain and humiliation of those who suffer with it.
Just like medicine anywhere else, I get to walk through life with people in the midst sometimes of their most difficult and challenging circumstances they've faced - a terminal diagnosis, bad news, poor prognosis - and also the most joyful times with people, like the birth of a new baby.
