Well if you watch/listen to his story, it was the resultant infirmity and emptiness of that life near the end of his life which helped him see his need for salvation, and thus renounce the devil and receive Christ for real, as he bluntly states it and challenges all to do.
Well, as I said, all those crazy stunts probably heled him come to Christ.
I watched the link, nothing like that on it.
But I could swear I heard him talk about Christ earlier in his life - in the midst of his stunt life.
