Rory and Joey Feek are incredibly grateful for the time Joey was recently able to spend out her hospice bed to play with their daughter, Indiana.

Rory wrote about the heartwarming photo the couple Instagrammed on Friday -- of Joey sweetly playing with Indiana -- in a new blog post on Sunday. The country singer said Joey, who's been diagnosed with terminal cancer, was initially prepared to never walk again, making her time out of bed even more incredible.

"We had some friends and family here at the house with us, and when the door to her bedroom opened up and she came out in the living room, we almost couldn’t believe our eyes," Rory, 49, shared. "We were all so proud of her, but I think Joey was even more proud of herself."

"A few minutes later, my wife had slid from the couch to the floor and was able to be something for Indiana that she hadn’t been able be in weeks and weeks. She was a mama again," he continued.

Joey, 40, played with and taught sign language to Indiana for the hour and a half she was able to get out of bed, which she had been "dreaming of being able to do." More so than ever, the couple is treating moments like these as a gift.

"Before Joey went to sleep this evening, I sat beside her and she told me that for her it's all come into perspective recently," Rory shared. "She said that when you’re lying in a bed day after day and you can do nothing and you don't know if you're gonna be here next Christmas, or next month or even next week… you suddenly become hyper-aware that today… that this moment -- is all you have."

And through all their struggles, Rory obviously still has so much love for his beloved wife.

"She might look different to you. But not to me," Rory wrote about remembering Joey in a video they did for their song "The Gift" off their 2011 Christmas album, A Farmhouse Christmas. "Yes, she's a few years older and the chemo and radiation have taken their toll on her physical body. But the same joy in her spirit and the same beautiful smile is still there, shining through. Cancer can’t take that away from her."
