A- Firstly I would be interested in how they found the religion and started feeling the faith, I would lose interested if they were brought up with it, but if there is a great story behind the faith then it makes for a more interesting read/listen. I would also be curious as to why their particular religion over others, not like a debate about whose is best but more an insight into why said persons religion is more suited to them.
B- Like I mentioned in part 'A', the why, but also like TDS said "What is god to you?" or to more "What is the higher power to you?", "What does your religion mean to you?"
Hopefully this helps, its not quite as elaborate as TDS's but just an input.
