Mark’s two houses are not the same kind of house: one is a temporary physical structure, the other points toward something eternal and spiritual, a distinction Paul draws out explicitly in 2 Corinthians 4-5. Secularism’s chief effect on the modern church has been to obscure heaven itself, trading the eternal structure for the temporary one. Recovering that distinction is what this sermon sets out to do.
The healing in the synagogue and the healing in the house run in close parallel, and the move between them is not incidental. When Christ enters Peter’s house in 1:29, he begins to make a new kind of home, one that anticipates the church as his own body. Four implications follow from that single, unremarkable detail of geography.
