Jeff discusses several issues: the flood, Jonah & the whale, Genesis’ creation account, and others.
The Bible is similar to a library. Lots of books there. Lots of books from different genres or styles there. Not all the books are historical non-fiction. Same with the Old Testament.
Some in the Old Testament is poetry. Some is parable. Some is absolute history. But not all is absolutely historical.
Did the Good Samaritan story really happen in the New Testament? Probably not.
Did Jonah really get swallowed by and remain in the belly of the whale? For three days? Almost certainly not.
