"Most marriages today have a tendency to accept sin in either spouse. One spouse becomes dominant and the other passive. The couple goes through life trying to manage sin rather than allowing God to change them from the inside out...A Christian marriage is committed to see sin put to death through the finished work of Christ and through the abiding Holy Spirit, who radically transforms us on a day-in and day-out basis. For the couple, this means:
- Constant repentance
- Constantly seeking forgiveness
- Constant openness to change "
