An adorable little girl with a rare blood disorder has shown the world what it means to be an "overcomer."
In a Facebook video that has gone viral, four-year-old Leah Carroll is seen in her hospital bed singing and dancing along to her favorite song, Mandisa's "Overcomer."
Her mother, Lindsay Carroll, uploaded the video Sunday, and it has received over 12 million views.
In the post, Lindsay wrote:
"My daughter has overcome two bone marrow transplants. She has spent the last 322 days away from her family and mostly in the hospital due to complications. However, she has the joy of the Lord and a love for music. Overcomer is one of her all time favs! Someone suggested I share it with you personally! She is such a light to all she meets....I hope she brings a smile to your face, too!"
Since she was six-months-old, Leah has battled severe congenital Neutropenia, a rare blood disorder that prevents the production of white blood cells that ward off infections. She currently suffers from graft versus host disease, and the road to recovery has been far from easy.
The video was also posted on Leah's Facebook support page, PrayersAndLoveForLeah.
Mandisa, whose album "Overcomer" won the 2014 Grammy Award for Best Contemporary Christian Music Album, shared the video on her Facebook page and asked her one million followers to send prayers to Leah.
"Leah: You are an overcomer in the truest sense of the word! Seeing the joy of the Lord on your sweet face inspired me so much. I'm praying for you, and believe that many of my friends on here will join me. Keep trusting Jesus, and fight on, precious one."
Below is the YouTube music video of "Overcomer." It features appearances by "Good Morning America" host Robin Roberts, former Olympic figure skater Scott Hamilton and former Congresswoman Gabby Giffords -- all of whom overcame serious challenges in their lives.
