So many things change when you first get married!
You and your husband are suddenly a family, just the two of you, separate from your parents.
We all know the Bible calls on our husbands to leave their parents and cleave unto their wives (Genesis 2:24). But this leaving and cleaving doesn’t mean that they aren’t still a part of their larger families as well. Their parents will always be their parents (although the roles and interactions definitely have to change after marriage).
So this reality brings with it a whole new role for newlywed women: Daughter-in-law.
