An official DoD article highlights the “positive role” SPC Benjamin Reynolds has in his unit, the 82nd Airborne currently deployed to Afghanistan.  Even those around him know what drives him:

Reynolds sites his faith as playing an important role in maintaining the positive attitude that so many in his unit admire. In the toughest of times, his beliefs seem to grow even stronger.

“I usually pray for my safety and those around me and use my faith as a motivator,” he said. “When God pulls you through something like that it’s an amazing feeling. It really reinforces your faith.”

Reynolds’ company commander literally couldn’t stop giving him praise: 

“He’s just a hardworking, honest kid. A lot of people make excuses all the time and Reynolds is not one of those people. You need somebody that you can always count on. No matter what, at the end of the day, you know you are going to get more than Reynolds can ever give you. He isn’t going to let anybody down. He’s not going to let the commander down. He’s not going to let his individual team leaders down. He’s just a positive influence in everything he does.”

That’s the reputation a Christian should try to have in his unit.
