It is difficult to tell from the report if Tebow disagreed with the church's stance on controversial issues (I doubt it since the same report states that he's a member of another Southern Baptist church), or if he's just not prepared to take on the challenges that would be bound to come (as if he hasn't already had to deal with plenty).
As a defender of the truth of Christianity, this story caught my attention. I can't help but think that if Tebow's church had taught him, not only what to believe but, why he can trust that his beliefs are, in fact, true; then maybe Tebow would be as confident defending the truth of his convictions as he is playing on the football field.
