The first time Sadie called for her fans to pray for Katie was through a photo she posted to her Instagram on July 29, 2015. Part of her caption encouraged fans to pray, saying it was the only thing that could help Katie recover.
"The only thing that can fix this is if we storm the gates of heaven," Sadie said.

The reason Katie is in such desperate need of prayers right now is because she just returned to St. Jude's to start a trial round of treatment that combines two types of chemotherapy. If the treatment works, Katie will need to continue it for the next two years.
We join Sadie in sending our heartfelt thoughts and prayers to this brave little girl and her family.
