"Duck Dynasty" star Sadie Robertson is urging fans to "storm the gates of heaven" in prayer for a little girl suffering from an inoperable brain tumor.

Last week, the 18-year-old model shared an Instagram photo of the little girl, Katie Joyce, lying in a hospital bed.

"This is Katie Joyce - Her family found she has a brain tumor and its on her brain stem which is inoperable," Sadie captioned the photo. "The doctors say we need a miracle. The only thing that can fix this is if we storm the gates of heaven. Writes comments of encouragement & if you known someone who needs prayer feel free to write it in a comment & I will pray for you all as well."

The Instagram post has received over 157,000 likes and over 9,000 comments, with many fans offering words of encouragement for the young girl and sharing their own prayer requests.

"Prayers coming her way. Never give up the fight. With our Heavenly Father and Savior, anything is possible. He overcame the world so we wouldn't have to alone," wrote one commenter.

"Praying for a miracle and peace for the whole family. I just lost my sweet Daddy to terminal cancer 2 months ago, and it is not something I would wish on anyone...especially a little girl who has her whole life ahead of her. We praise you Lord, and we ask that your will be done. Amen," added another.

Wrote yet another, "I taught Katie art for a week this summer and even though I didn't know her very well she had the sweetest spirit and just radiated joy! We all need someone like Katie in our lives to remind us that God is good and with life comes joy and happiness even in dark times. She is in my prayers."

This is not the first time the "Dancing with the Stars" alum has asked for prayers for a sick fan. In March, Sadie star shared a photo of a young boy no more than four years old strapped into wire monitors on his hospital bed. She urged her followers to pray for the child, Sam, as he was expecting to endure an additional round of chemotherapy treatment the upcoming weekend.

"This little one is going through another round of chemo and he really needs all the prayer he can get," Sadie wrote in the caption. "He is a precious little angel... Please lift him up in prayer today #samstrong."

Robertson, who published Live Original: How the Duck Commander Teen Keeps It Real and Stays True to Her Values a few months ago, often reminds her social media followers to remain faithful, offering words of inspiration and quotes from Scripture.

"In life we get scared! We get insecure! We get worried! We get stressed! Sometimes we have anxiety! BUT we are not alone!" she wrote in a recent Instagram post. "We serve a God who is bigger than our fears, insecurities, & worries! He has already defeated it all at the cross. so trust that. Be brave & courageous because we have NOTHING to fear!"
