In the first half of the Book of Ephesians, the apostle Paul lays out the Christian’s new identity in Christ. In the second half, he provides the “so what,” or the ramifications. As he outlines what Spirit-filled living looks like (Eph. 5:18ff), he envisions a community in which people show Christ’s love by serving one another. And one of the places where such service happens is in the household—where in his day he would have found spouses, kids, and slaves under one roof.
