Grandchildren are God's reward for not killing your kids.
I don't know how your theology works, but if Jesus has a choice between stained glass windows and feeding starving kids in Haiti, I have a feeling he'd choose the starving kids in Haiti.
Nothing is more dangerous than to live out the will of God in today's contemporary world. It changes your whole monetary lifestyle...Let me put it quite simply: If Jesus had $40,000 and knew about the kids who are suffering and dying in Haiti, what kind of car would he buy?
