Before playing one of the world's most violent sports, Curtis Martin would do something decidedly calmer. The former New York Jets running back read Psalm 91 prior to each game. The passage asks believers to declare their trust in God, who serves as "refuge" and "fortress." The message is unexpectedly passive considering the context, but the healthy dose of perspective helped Martin delineate his life on the field, which he could take responsibility for, and his life elsewhere, where fate, luck, and maybe even the divine played a larger role.
