Tebow cancels talk at controversial Dallas church

"We had planned for him to speak very positively about the difference Jesus Christ had made in his life," Jeffress said.

Tebow won two BCS championships and the Heisman Trophy at Florida, but he has struggled to make it in the NFL. He barely played last season after the Jets traded for him from the Denver Broncos, where he started much of the season in 2011 and won a playoff game.

Tebow is a devout Christian who has built a large following through his faith. He has addressed church audiences before. Last year, he spoke to about 15,000 people gathered at an outdoor Easter service north of Austin.
