“What does God have to say to single mothers?”
Okay, not funny. More than a few single mothers — widows, abandoned wives — get little or no choice in the matter. Still, many young women these days elect to bring a child into the world under less than optimal circumstances, in which case much of what the Lord would say to single mothers is likely to be the same sort of thing he would say to people who have sinned in other ways.
Even “sin no more” was also said to a man. So there is that.
