This sermon, as part of the "In Christ" Ephesians series, uses the modern idea of a "smart home" as a launching point to explore the "original smart home" — a household ordered by Christ. The message walks through how the gospel transforms every relationship under one roof: wives are called to submit not as command but as a willing gift that lets husbands lead, while husbands are called to a sacrificial, sanctifying, sensitive love modeled on Christ's love for the church; children are called to obey (for a season) and honor (for a lifetime) their parents.  Woven throughout is historical context about the low status of women, children, and slaves in the first-century world, contrasted with Paul addressing each group directly as full persons before God — closing with the reminder that everyone in the house, regardless of earthly power, ultimately answers to Jesus.
