""What is the greatest surprise you have found about life?" a university student asked me several years ago. "The brevity of it," I replied without hesitation. Time moves so quickly, and no matter who we are or what we have done, the time will come when our lives will be over. As Jesus said, "As long as it is day, we must do the work of him who sent me. Night is coming, when no one can work" (John 9:4)."
