"Away in a Manger" has that line that I've always questioned: "The cattle are lowing, the Baby awakes, but little Lord Jesus no crying He makes." How do we know He didn't cry? In addition to being fully God, Jesus was fully human, too, right? And I've never met a newborn that didn't cry, among other things.
Pastor Petersen over at Cyberstones does a nice job of removing the romance of the manger...and he's spot on. Click here to read his post "The Poor Baby Wakes and Bawls."
