I believe the Bible. I am curious about the reference to a Lake.
Everyone was well aware of the Oceans.
I believe, as well. I also see the language on many levels, so I try not to become absolutist over precise interpretations, since we didn't write it! God did, using human beings to carry out the physical manifestations.
Regarding the lake v. ocean: I'm just fooling around with metaphysics here, but a lake can be contained within a realm; but someone could ostensibly swim an ocean to another realm and beg for asylum!
