Tonus -I said "we should want to know." It is natural to want to know what you are about to get into, especially if it's a decision that will last for an eternity. It is also natural to think well of someone who prepares us, but to be highly suspicious of someone who will not quite explain the most important and crucial facet of our lives.
I would say the most important and crucial facet of our lives is the present, the here and now. 'Should want to know' seems more of a personal preference. Maybe not everyone wants to know. I personally don't concern myself with the afterlife since whatever it is I seem to have no say so in it.
If our defintion contrasts with that of God, we are wrong, aren't we?
Yes we would be, because God is a separate person from us, which was the point of my comment.
