Practical Faith and Reason

It is a principle of human practical wisdom that I am not going to live forever. Or, if one were to deny it the title of "first principle," we can surely say that it is a major step forward in young people's lives when they realize that this is true. It also seems, however, that one of the most basic principles for Christians to grasp - the basis of all Christian practical wisdom - is that I am going to live forever. As C.S. Lewis put it: we have never met a mere mortal. Where does that leave us in reconciling faith and reason at a practical level?
