Jordan Spieth is earning worldwide acclaim, not just for his skills in golf but also for his remarkable humility and display of devout Christian faith.

On Sept. 27, Spieth earned golf's top spot by winning the FedEx Cup. His incredible moves landed him the $10 million Tour Championship. This year, Spieth managed to make five wins, including two majors. His total earnings have already amounted to $23 million.

At just 22 years old, Spieth has a golfing career that looks very promising indeed. He is already being compared to the former golfing champion Tiger Woods. However, it is only on their golfing prowess that the two are similar, since Spieth has a clean-cut and wholesome image, a far cry from Woods' tarnished image, which is riddled with disastrous extramarital affairs.

With Spieth's level of success, other golfers might get obsessed in improving their game and doing everything they can to remain competitive. But Spieth is actually more concerned about improving his relationship with Jesus Christ than further improving his game. The golfer regularly attends the PGA Tour's Christian group with his good friend and fellow golfer Bubba Watson.

"He goes to Bible study with us on the Tour here," Watson said, according to the blog God Reports.

It is also inspiring to see that Spieth has maintained his humility despite his many victories. In recognition of his recent win, Spieth decided to celebrate at the Christian-operated Chick-fil-A restaurant as opposed to a lavish victory party in a fancy restaurant or hotel. It is even worth noting that he still drives the same Yukon truck from his youth, and is in no hurry to trade it up for a more ostentatious car.

Spieth also dotes on his autistic sister—15-year-old Ellie. "She's my inspiration," Spieth told the UK's Telegraph about his sister. "She's the funniest member of our family. I really love spending time with her. It is humbling to see her and her friends and the struggles they go through each day, which we take for granted. They are the happiest people in the world."

Many people believe that it is Ellie who keeps Spieth grounded. "We talk about how much he loves his sister. She's someone he loves and who has kept him grounded," Michael Earsing, president of the Jesuit College Preparatory School in Dallas, where Spieth graduated in 2011, told the Catholic Herald.

Athletic director Steve Koch said: "Jordan is just very genuine. He says what he believes. He believes in supporting others, taking care of others before he takes care of himself."
