My earthly heroes, if you wanted to call them that, are people that in my mind have done two things with their lives: one, they've really communicated Christianity effectively to their culture - and those are people like Billy Graham, and Francis Schaeffer, and C.S. Lewis, and people like that.  And i also respect those same people for the fact that they managed to keep their personal house in order during the long haul.  Those people are ... the models that i would strive to follow after in the long term.
