Sadie Robertson, star of “Duck Dynasty,” is calling on her fans to “storm the gates of heaven” for a little girl suffering from an inoperable brain tumor.

On Wednesday, July 29, Robertson posted an Instagram of the girl, named Katie Joyce, prompting an outpouring of support from the reality TV star’s audience.

”The doctors say we need a miracle,” Robertson wrote in the post, which had racked up 157,000 likes and nearly 9,000 comments as of Wednesday morning. “The only thing that can fix this is if we storm the gates of heaven.”

Robertson wrote in the Instagram caption that Joyce’s tumor is on her brain stem, and she rallied fans to pray for the child and leave their words of encouragement in the comments. The “Dancing with the Stars” season 19 runner-up also invited her followers to leave comments about their loved ones who need prayers.

“My daughter died from a brain stem tumor,” one commenter wrote. “Since then we have learned a lot about the treatments. We have information that could save this girls life.”

“Praying for this sweet girl,” another commenter wrote. “She’s strong and will fight this!”
