Scott and I (Sue) are a couple of ordinary Christians who found ourselves in an all-too-common situation: a disappointing, miserable, and failing marriage.  We could hardly understand how we got into that state of affairs.  Twenty years along in what we thought had been a basically happy marriage, we were at an impasse.  We were full of frustration, confusion, and anger, each convinced the other was primarily at fault for landing us in our predicament.
