According to the Denver Post, Tebow turned to the Bible, quoting Proverbs 27:17: "Iron sharpens iron, so one man sharpens another."
Tebow's motivational message worked. The Broncos put together their third fourth-quarter comeback since Tebow took over for starter Kyle Orton, rallying past rival San Diego for a 16-13 overtime win.
"He said iron sharpens iron and men sharpen other men. And I think that's totally true," rookie linebacker Von Miller told The Post. "He gave us a great speech. We came out (for the game) fired up. And that was a wrap."
Tebow, when told of his teammates' reaction to Saturday's speech, was touched.
"It was a huge honor," Tebow told The Post of being given the chance to speak. "I just tried to share from the heart."
For the first time all season, Tebow completed at least half of his passes Sunday, going 9 for 18 for 188 yards and had strikes of 39 yards to Eric Decker and 23 to Dante Rosario on the game-tying drive late in the fourth quarter.
"I've never seen a human who can will himself to win like that," Miller told The Post.
The Broncos (6-5) are 5-1 under Tebow and have forced their way into the race for a playoff spot. They face the Vikings in Minnesota on Sunday.
