A pair of LDS missionaries stopped by a few hours ago, and as I and the boys were headed out for a walk, I was unable to speak with them for very long.
However, we set up a time for them to come by again.
My questions for them will be (and are all interrelated):

Why is the God of LDS different that the God revealed in the Bible?

How do I know that Joseph Smith's revelation was really from God?

Why should we trust Joseph Smith? Isn't this all dependent on his word?

Why isn't the NT as we have it today reliable?

How does one distinguish that a "burning of the bosom" is God leading and not just heartburn?
What would you ask them?
Any thoughts or pertinent scripture references are appreciated.
