In case people have not seen this site as yet it is a very useful resourse if you are debating theology with Christian believers.
Trust me they do not like answering questions that are based on biblical texts. You ususlly get answers like you are reading that out of context or misinterpreting it.
When you ask what is the context that was intended the argument usually stops
I shut down a discussion about abortion using quotes from this site, people were not willing to discuss the fact that their God had ordered the slaughter of children.
