Tony Campolo writes that when his son was a young boy he once defined faith as "believing what you know isn't true." I can see how easy it is for many to arrive at that definition of faith, but faith for me has never been that. I would rather define faith as believing in that which you think really is true though you cannot absolutely prove it.
As long as human knowledge is partial (and I believe that will always be the case, at least on this side of death) faith is necessary (for the atheist as well as the Christian).
I have always been struck by the words of Harry Emerson Fosdick quoted by John Claypool when he was trying to continue with his life after he had learned that his 8 year old daughter, Laura Lue, had leukemia (she later died of it): "A man can put off making up his mind, but he can't put off making up his life."
He was pointing out the truth that we cannot refuse to live until all our questions are answered. Answers will come only by and through our living (and Christians believe at the end of our living). The Apostle Paul was right: "For we walk by faith, not by sight."
