I have a friend who lived in open adultery for eighteen years. He was not a Christian and was not shy about his lifestyle. His wife, like Mable, knew most of his sins. My friend’s wife chose to honor God by staying in the marriage. She did not have to because she had biblical grounds for divorce, but she decided to stick it out, which the Bible does not prohibit. There is no doubt that God gave her supernatural grace to persevere through her husband’s many sins. He finally repented of his sins in June 1988, the day God regenerated him. Since then, he has faithfully loved and served his family in the context of a local church. The story of my friend is analogous to Biff and Mable’s story.
