Chapter 4 says a blessed family is a micro-church and adds that many people should be able to visit such a family. That detail matters. It means a heavenly household is not merely morally clean. It is socially open, connective, and life-giving.
This resists a private model of holiness where the family exists only to preserve itself. In the chapter’s logic, holiness creates hospitality. The family becomes a node in a wider network of blessed families, kinship, and mutual support.
That makes the household missional without turning it into a program. A home faithful to heaven should feel inhabitable to others, not sealed off from them.
