Joey + Rory Feek are asking fans all over the world to participate in a prayer vigil for Joey as she continues to battle cancer.

They canceled their remaining Farmhouse Concerts after receiving the terrible news that Joey's cancer -- for which she recently underwent surgery, radiation and chemotherapy -- has not responded to treatment. Her doctors have told the husband-and-wife duo that there's nothing more they can do.

The couple have made the tough decision not to seek further treatment, and in a new post to his blog, This Life I Live, Rory reveals they've been visiting Joey's family in Indiana.

"She is spending important time with her mama and daddy and three sisters in the farmhouse she grew up in," he writes. "They’ve swallowed hard and had some difficult conversations that they didn’t want to have ... But mostly, it’s been beautiful."

He reveals that his wife's condition is deteriorating. "Most of Joey’s immune system is gone now and she’s thin and frail. Where she once jumped out of bed before the sun rose to rush out to her garden… she now quietly sleeps away most of the days. I lie beside her at night and I hold her hand and listen to her breathe. And I pray."

Rory also thanks fans for the enormous outpouring of support and letters the couple have received. "I read them to Joey and the tears stream down her cheeks and mine. And once more we smile and look at each other -- in awe of this extraordinary, ordinary life we live. For better or worse," he says.

"I said those words to her at the alter on June 15, 2002. But today and each day since our wedding day has been my opportunity to show her that I mean those words. And I do mean them."

He is asking fans to join them in praying Joey's prayer, which is simple: "Pray for a miracle ... And even more so, for peace with His decision."

The couple have set a time and date for fans and friends to join them in prayer on Thursday, Nov. 5 at 8PM CST.

"You can call it a prayer vigil, or a moment of silence, or what it actually is… a husband asking for help for the woman he loves," Rory writes. "But please, one thing I ask… don’t just pray that Joey is healed. Yes, pray for a miracle. But also pray for peace in her heart, and ours, if God chooses not to let this cup pass from her sweet lips.

"His will, not ours."
