Believing without seeing

A friend of mine is starting a new life today. She has wanted it for a very long time, and after some soul searching she has finally decided to do it. (It's not the kind of life I'll willingly take, so when she told me about it I wasn't so sure. But I support her decision, because, as someone pointed out, "It's not 'bravery' to do what you want to do, you're just an idiot if you don't.")
Anyway, my friend left a story about faith from Paolo Coelho's blog, "Believing Without Seeing". And this, at least, has put my mind at ease, keeping faith that my friend is in good hands.

Believing without seeing
By Paulo Coelho

An emperor said to the Rabbi Yeoschoua ben Hanania:

‘I would very much like to see your God.’

‘That is impossible,’ said the Rabbi.

‘Impossible? Then how can I entrust my life to someone whom I cannot see?’

‘Show me the pocket in which you have placed the love of your wife, and let me weigh it in order to see how large her love is.’

‘Don’t be silly; no one can keep someone’s love in their pocket.’

‘The sun is only one of the works which the Lord placed in the universe and yet you cannot look at it directly. You cannot see love either, but you know you are capable of falling in love with a woman and entrusting your life to her. Is it not clear then that there are certain things in which we trust even though we cannot see them?’
