In a famous Christmas sermon, the great reformer Martin Luther described how Mary had to give birth in a stable because there was no room in the inn. Then Luther turned to his congregation and said, “You think to yourselves, ‘I wouldn’t have turned the couple away. I would have given them my own place.’” To which Luther replied, “No, you wouldn’t. If you would have been so generous, so sacrificial, why aren’t you now? You meet Christ in your neighbor every day and you are not generous or sacrificial to him now.”
