I was talking about a tree being known by its fruit. I am also talking about public figures with a record. IOW, for instance, Obama has no fruit. To me Mother Teresa model is one of repentance with surrender and Martin Luther model is one of reformation and common sense. I am not saying God did not call Martin and use him mightily.
After the main surrendered to the Father's will model of The Lord Jesus Christ, I think the Bible stories about hero's of faith or not are there as guides for us. Samuel was about the most surrendered for his whole life. At the end He was frustrated about Israel not understanding His message. St.Paul arrived there though his experiences. Joseph is a neat model. etc.
JPII is interesting. He was definitely a politician to begin with but His Faith model during his Parkinson's was incredible. A wonderful example of what the Apostle Paul is saying when God says my grace is sufficient.
