The Queen of Christian Pop says that what she thought would be an impossible recovery has turned into a miraculous one.

Amy Grant underwent "unanticipated open-heart surgery" on June 3 to deal with a condition she has had since birth but was only recently discovered by doctors.

"The only way I can explain my experience would be to ask you to imagine a non-runner who was signed up for a marathon," she says in an update on social media. "I didn’t want it, but I had to have it anyway and it was a week ago Wednesday."

Doctors discovered Grant's condition, called partial anomalous pulmonary venous return, at a routine checkup. It was quickly decided she should undergo surgery to repair the condition.

Grant says that she's been overwhelmed with messages of support and prayers offered.

"People I worked with decades ago, people who have come to my concerts or listen to my music, my work family, people on social media, and my own friends and family all offered their prayers."

Grant says that "now, 10 days later, I just want to say, from the moment I went to the hospital, if it really were a marathon race, I felt like I got into that runner's block and as soon as it was time for the race to start there was this massive West Texas wind at my back.. just pushing me through."

She says that even the biggest fears and anxieties she was facing suddenly simply "felt like nothing more than just a deep breath and something supernatural pushed me through it.

"My recovery has honestly felt miraculous. And so I want to say thank you to each person who said a prayer for me. Prayer changes everything. Let’s keep those prayers going for our country and let's turn all the brokenness into love and seeing each other. I love you."
