Neglect of this truth is pervasive in the modern church. One of the most difficult things for modern men to understand is how they are responsible for their wives. Men come into a marriage pastoral counseling session with the assumption that “She has her problems,” and “I have mine,” and the counselor is here to help us split the difference. But the husband is responsible for all the problems. This is the case for no other reason than that he is the husband.
This does not mean that the wife has no personal responsibilities as an individual before God. She certainly does, just as her husband has individual responsibility. They are both private persons who stand before God. But he remains the head, and just as Christ as the head assumed all the responsibility for all the sins of all His people, so the husband is to assume covenant responsibility for the state of his marriage. If a husband says that he objects to this because it is not fair for him to be held responsible for the failings of another, he is really saying that he objects to the gospel. It was not “fair” for Christ to assume responsibility for our sins either. But while it may not have been fair as we define it, it was nevertheless just and merciful.
