I really do like this question - I think I'd go for interchanging he and she at random... not allow anyone to pin down a specific gender on the word. I am sure that gendering the Bible like this will make some people uneasy, especially (sadly) if given the female persuasion...
I was inspired by this question on Doug Pagitt's blog, check the title link.
I also like the "they" concept, as the Bible's own nature is an argument for community. Written by so many, inspired by a triune God - a story of people, not just a person - even if Christ is central...he is there for everyone else..
What do you think?
