I read this today in Jim Wallis' new book Seven Ways to Change the World and I can't think of a better response:
Questioner, to Billy Graham on his last visit to Harvard:
'Since Jesus said "I am the way, the truth and the life, no man cometh to the Father but by me" doesn't that mean people from other religions - Jews and the rest - are going to hell?'
Billy replied, 'I'm sure glad God is the judge of people's hearts and not me! And I trust God to decide those questions justly and mercifully.'
The student was disappointed and pressed further, 'Well, what do you think God will decide?'
Graham demurred, 'Well, God doesn't really ask my advice on those matters.'
