God knows exactly what He is doing when He works out His will in our lives - and we see God's glory every Sunday in Tim Tebow.
I'm with you!
He is so in everyone's face about his faith he forces people to think. I'm sure there are a lot of people who initially are turned off, but I believe some get convicted by the Holy Spirit and think twice about what they are criticizing.
My wife once commented to me how she was turned off by a street preacher standing on a corner with a bullhorn. She thought it wasn't very dignified. We talked about it. My point to her was you don't know how many walk by that Preacher and they hear The Gospel for the first time. I think Tebow's exuberance in expressing his faith is a little like that. What's really exciting is the more you learn about him the more you see he lives his faith.
