If you're a Bible literalist and you believe that you will see Armageddon in your life time, then why would you bring children into the world? How can you?
I see these people on television with large families and each and everyone of them is preparing, in some way, for Revelations to be fulfilled. For a few families, it's the reason they have so many children ("To raise up a Quiverfull for God."). Why would you do that? What is honorable and loving about having a bus full of children just so you hedge your odds on a few of them getting to heaven? What's honorable or loving about having one child with those expectations?
There is a reason I ask this, but I'll save it for comments.
