How do you know?

I found this statement on the net, "...the original autographs, are the written Word of God, divinely inspired and completely inerrant and factual."

How do you know they were completely inerrant and factual if we don't have them?

 

Do we receive a burning in the bosom or is it pure fideism? Are we to separate faith from reason and just believe we are reading scripture without any reason for doing so? If only the originals are inerrant how do we know they are inerrant if we do not have them now? If you quote scripture, how do you know it is scripture considering the modern view of the last section of Mark, John 8 and 1 John 5:7? How can I know if what I'm reading in the Bible is part of scripture or not? If your convictions are derived from scripture, could they be wrong since we do not have the original mss, which are the only inerrant source of faith, and be absolutely wrong? If our understanding of God and His nature comes from the scriptures and the Bible we have is a copy with errors, could our understanding of God be in error? How important is our epistemology?

I ask these questions, not trying to form some Socratic dialogue, but seeking real answers. These are the questions often asked by atheists and once in a while by Muslims.

Thank you.
