I re-read this short poem by John Piper, for Christmas, made into a book. It's really too short for a book.
It's a good antidote to the sentimentalism of Christmas, which cost families their babies' lives. Just a couple of brutal lines about 3/4 into the poem pack quite a punch. Jesus came into this sinful, harsh world to redeem the worst of circumstances. Mary's birth of Jesus was one of these - Christmas was no cake walk for Joseph and Mary.
