"I think for a lot of people that believe, they think 'Well I'm OK no matter how this turns out,' which really takes the pressure off a putt or a shot.
"It doesn't mean that everyone that believes in God is going to win the tournament, I think that would be a mistake to think that's what it does."
Rotella has worked with 74 winners from the men's, women's and senior tour throughout his career, gaining a unique insight into what helps the world's top golfers succeed at the very highest level.
He has explored the idea that a belief in God helps performance
"That's a big piece of the puzzle that these players are trying to deal with," he said.
"On the other hand, you try to get these players to understand that God probably doesn't really care if you win a tournament or make a putt or hit a good shot.
"If God did care about that, he's probably not the God that we'd like to believe in, so that's where it gets fascinating.
"But I think it allows them to be happy away from the course, and I think the other part of it is that when you're living on the road all the time, to have a belief in a God keeps you on the right track in terms of values and morals and how you live your life.
"I think a lot of players feel there's a sense of destiny that God gave them a gift of God and a passion for golf, because God wanted me to do some incredible things with my life."
Zach Johnson, who won the Masters at Augusta in 2007, concurs with Rotella that his religion has helped provide perspective on his life.
"I am a believer; I believe in Christ, I believe he died for me," the 37-year-old American, who is away from his family from months at a time and competing under constant pressure told CNN.
"I feel I'm ultimately blessed that I play this game for a living and the perspective on it is that I don't want my identity to be wrapped in the fact that I am a golfer.
"I'd rather be wrapped in the fact that I am a Christian. I feel blessed and lucky that I can play this sport. It's a job -- that's crazy -- but I will never forget my number one priority and that's him."
Like many of his fellow Bible group attendees, the opportunity to talk about Christianity offers a refuge from the constant media spotlight which surrounds the Tour.
"It gives me peace about my days," Johnson said of his faith.
"If I have a bad day, it's irrelevant; if I have a good day frankly it's irrelevant. My scorecard is irrelevant. The best part is when I get here and I can see my family.
"I think a lot of us Christians out here like to utilize our platform and witness what is important in our faith. If anything I would like to witness when I have a bad day, that's really what it boils down to."
The bond between members of the Bible group remains strong, with each week offering a new opportunity to discuss a religious tenet.
And as the word spreads, the group's attendance figures are growing with the next generation of players fiercely proud of their religious faith.
"If you look at it from a sheer numbers stand point of view, you think 'Wow maybe that God thing is working' because there are so many believers on Tour," added Crane, who regularly discusses religion with his 105,000 followers on Twitter.
"I think it's because there are so many ups and downs with the game of golf and guys that have been out here for five to 10 years, and all of a sudden you expect to play a certain way.
"Those expectations are very hard to deal with. When you first come out on Tour you're extremely nervous, you want to do well and your identity is so much wrapped up in how you play and that's how other people see you.
"You think that's how people like you, based on your performance, and with my relationship with Christ I get relief from that."
