Why is the Bible True and other Scriptures False?

This has been a question that has plagued me for a long time, especially given my extensive study of other scriptures in addition to our own and my thorough study of historical/critical reflection on the Bible.

It seems to me either:

A. we must ACCEPT the premise "our scripture is true, theirs are not" on FAITH alone
or
B. we must DEMONSTRATE the premise "our scripture is true, theirs are not" RATIONALLY.

I would relish hearing a sound and sane discussion on this issue.

Thank you.

In Christ
