A wise old friend of mine went to seminary many years ago. He tells the story of how he was supposed to do Bibles studies with people in the community. He had been through the classes and knew how to argue the finer points of theology, he knew the prophecies, and he knew how to prove everything he was arguing, from scripture. An elderly man let him into his home and they started studying. After about ten minutes, the man showed my friend to the door and told him the words that forever changed his life and ministry. He said "You would make a great attorney for your faith, but you aren't much of a witness."
