Abortion. Feminism. Online harassment. Social justice. Women's "no"s are constantly doubted and eroded in our culture. Saying "no" and sticking to it - and, especially, doing that where other women can see it - is a political statement.
I know several couples who experienced adultery in their marriages, but because in each case there was a wife who was willing to pray and a husband open to allowing God to change and restore him, the marriages are still intact and successful today. Only prayer, a submitted heart, and the transforming power of the Holy Spirit can work those kinds of miracles.
