Fighters are raised into MMA. It's more about what's internal, not what's God given. When you have a great fighter like Rickson Gracie or Fedor Emelianenko-they're greater than the others because they have an internal spiritual being that separates them from the rest in their craft. They have the warrior spirit.

On the field is a place where you can just let it loose and react to everything with violence.
