Well I know quite a lot of people that think they know. They act like they know, and preach like they know.
Yes they do.
However, exactly how can someone "Know" there is an afterlife until they have died?
I have no problem with folk believing in an afterlife, in fact I do, but I cannot "Know". It cannot be verified and if I am going to be honest, at least with myself, I must admit I might well be wrong.
As for the word of God. That means the bible is divinly inspired and cannot be wrong (there is also people believing that you know.)
Yes, there are also folk that hold that position. Yet even you have pointed out places where the Bible is verifiably wrong. Actually there are many, many, many such places.
If I am going to be honest, at least with myself, I must admit those errors that are verifiably wrong.
The Bible can still be divinely inspired even with errors. If the purpose of the Bible is to teach folk how to best live their lives, to provide a view of how a peoples saw their heritage, to provide explanations that worked within the framework of the era, culture and peoples who wrote it, then it can be inspired even if not factually true.
A good example is the multiple creation myths included in Genesis. While they are factually wrong, they do illustrate two aspects of GOD, the transcendent overarching God of Genesis 1 and the personal, hands on, companion God of Genesis 2. It also explained other facets of their culture, why we work six days and take a day off for rest, why we fear snakes, why childbirth seems harder for humans than other animals, why we must work and farm instead of simply grazing like other critters.
These and others could well be inspired messages.
