(CNN) -- Like the other American who volunteered to help others in Africa and ended up with Ebola, Nancy Writebol is driven first and foremost by her fervent faith.
Still, that doesn't mean she doesn't need -- or deserve -- a pick-me-up.
So, after arriving at Atlanta's Emory University Hospital from Liberia, Nancy Writebol asked for -- and received -- coffee from Starbucks. That was a definite plus about being back in her home country, though her husband acknowledges she has a long way to go to beat the deadly disease.
"I don't believe we can say she is in the clear, (but) I would say she is in very good hands," her husband, David Writebol, said Friday. "... I am praying like never before."
On the same day he spoke about his wife's illness, the other infected American, who is being treated at the same Atlanta hospital, spoke publicly for the first time.
Dr. Kent Brantly said in a statement that he is receiving "the very best care possible" and "growing stronger every day."
Brantly and the Writebols talked about what led them to Liberia, where they thrust themselves into the midst of poverty and disease with a mission focusing on those in need. They also spoke about their struggles now to overcome Ebola.
Brantly, 33, went to Liberia with his wife and two children last year to serve a two-year fellowship through a Samaritan's Purse post-residency program to practice general medicine.
But everything changed when Ebola started to sweep through West Africa. Brantly got a new role as medical director for the Samaritan's Purse Ebola Consolidated Case Management Center in Monrovia.
"I held the hands of countless individuals as this terrible disease took their lives away from them," he said Friday. "I witnessed the horror firsthand and I can still remember every face and name."
It was in Monrovia where Brantly said he "immediately isolated" himself after first feeling ill. Three days later, his Ebola diagnosis was confirmed, though it didn't trigger the emotional response one might expect.
"When the result was positive, I remember a deep sense of peace that was beyond all understanding," he said. "God was reminding me of what he had taught me years ago, that he will give me everything I need to be faithful to him."
Two weeks after that diagnosis, Brantly said, "My focus ... remains the same -- to follow God."
That strong Christian faith also echoed throughout David Writebol's comments about his wife.
Married for 40 years, the Writebols have traveled the globe focused on their faith and their desire to help others.
They are an ocean apart now, though plans are in the works to bring David Writebol from Liberia to be with his wife in Atlanta. When they do reunite, David said, "I would give her a kiss. Hold her."
After that, the couple wouldn't necessarily go back to the comforts of America and more coffee from Starbucks. Ebola might have derailed them, but it hasn't changed their purpose in life.
"We aren't going to stop our ministry," David Writebol said. "We believe we can serve wherever God sends us."
