Mark Hall, the lead singer for the internationally known Christian band Casting Crowns reportedly has had successful cancer surgery.

“Mark is out of surgery. Everything went really well. Dr. says textbook operation. Just like we prayed for. I told the doctor that he might possibly be the most prayed for Dr. on the planet today. He will be in recovery for a while. Thank you so much for your prayers,” noted an update on the band’s Facebook page posted shortly before 2 p.m. Wednesday.

The singer’s wife Melanie took to social media to thank Christians around the world for their outpouring of support and prayer.

“I’m completely humbled by the number of people that have expressed their love for us and are interceding in prayer. There are no words to express the gratitude in this wife’s heart. Thank you for praying for us. We have had friends and strangers from all over the world tell us they are praying — an orphan school in Kenya, neighbors we just met, long lost high school friends, Christian music artists from their concerts, schools, offices, pastors in South Africa, chaplains in the Army, churches, radio DJs, fans, missionaries in Brazil, and countless others I couldn’t begin to name. Thank you. Your prayers are felt,” said Melanie in the post.

She said that she and Mark are asking people to pray how God can use this trial to allow them to witness to their friends as much as they pray for his recovery.
