In this teaching, Alan Platt issues a bold and urgent call for the Church to ReThink — not simply adjust its programs, but fundamentally transform the paradigms that shape how it understands its very reason for existing. Beginning with the conviction that the Church does not have a mission but that the mission has a Church, Alan works through nine critical areas where a shift in thinking is needed: from church growth to church on mission, from encouraging to equipping, from secular vocations to sacred callings, and from measuring church activity to measuring Kingdom impact, among others. At the heart of this rethinking is a return to incarnational mission — being present in the community not as an institution that ministers to people, but as a movement that lives among them, carrying the Fathering heart, Faithful character, and Fruitful actions of Christ into every neighbourhood. Inspired by the story of Nehemiah, it is ultimately a call to rebuild — to take Faith, Love, and Hope into the spiritual lostness, social pain, and systemic brokenness of our cities with the same urgency and intentionality that rebuilt the walls of Jerusalem in just fifty-two days.
