Jesus could have judged the woman caught in adultery (John 8:3-11). She was guilty, after all. The crowd knew it. She knew it, too. And according to the strict law of Moses, she deserved death by stoning.
Rocks in hand, the men dragged the woman through the streets, and asked Jesus for her final verdict. Instead of condemning her, Jesus forgave her.
That story from the book of John is helpful for couples whose marriages have been assaulted by the betrayal of adultery.
