A photo of a young girl seemingly peacefully asleep, surrounded by pillows and a colourful blanket where her long black hair rests, has been making the rounds on social media site Facebook.

The young girl in this post, which has already been shared over 2,000 times, is 15-year-old Jahi McMath, who has been brain dead for more than two years now due to complications from a routine tonsil removal surgery. Almost all patients in a similar state never get to walk, speak or open their eyes again.

Although the California coroner already issued Jahi's death certificate back in 2013, her Christian family still holds on to the belief that one day, their young girl will wake up and fully recover. After all, Jahi's heart is still beating, her lungs still allow her to breathe, and even her hair keeps on growing.

Jahi's mother, Latasha Nailah Winkfield, believes that her daughter is "still asleep."

"I don't use the word 'brain-dead' for my daughter. I'm just waiting and faithful that she will have a recovery. She is blossoming into a teenager before my eyes," Winkfield said in an earlier interview with NBC Bay Area.

She also always proudly wears a pin which reads "Jahi's Life Matters" on her chest.

"Jahi is healthy from the neck-down. She just has a brain injury, and I understand those things do take time to heal," Winkfield told the San Jose Mercury News in a separate interview.

Jahi's father, Milton McMath, has an equally strong faith in God and his daughter. "I will not give up on Jahi, period. I will pull a trigger on myself before I pull the plug on her," he also told Mercury News.

Some Facebook users, however, do not understand the plight of Jahi's parents, even questioning God in their posts.

"I'm sorry it's modern medicine and modern technology. If God is so powerful and keeping her alive take her off the man-made machines and let's [see] what your God does. I fully understand your fate but it's time to face reality," one commenter said.

Others, however, were very supportive, urging Jahi's family to keep the faith.

"Jahi Will Rise," user Eno Inyang wrote after she reposted the photo. "A recent picture of beautiful Jahi, doing very well, hair, skin and all very healthy, growing into a beautiful young lady in front of her mother's eyes."
