This is an interesting viewpoint on the global flood controversy within theological circles. It is a small, but interesting, debate on whether their was a global flood or a local (regional) one. Like most theological debates, the controversy is greater than the debate itself.
Take a few minutes and listen to what Dr. Heiser is postulating, it is not that preposterous. Go back to Genesis and read over the scriptures in which he is using to make his case. You just might discover how wrong your biblical worldview has been this whole time. Remember, the Bible was written for us, not to us. It is important to read the test through the writers eyes and not through 21st century eyes of the western world. You just might discover a whole new biblical world that was hiding in plain sight all this time. God Bless.
