Husbands are not Christ. But they are called to be like him. And the specific point of likeness is the husband's readiness to suffer for his wife's good without threatening or abusing her. This includes suffering to protect her from any outside forces that would harm her, as well as suffering disappointments of abuses even from her. This kind of love is possible because Christ died for both husband and wife. Their sins are forgiven. Neither needs to make the other suffer for sins. Christ has borne that suffering. Now as two sinful and forgiven people we can return good for evil.
