Paul Barnhardt examines 1 Timothy 3:14–15 to reflect on three biblical pictures of the local assembly: the house of God, the church of the living God, and the pillar and ground of the truth. Drawing from his personal history with the Barrington Gospel Hall, Barnhardt explains that the house of God requires orderly Christian behavior according to divine design, while the church of the living God emphasizes the active presence of Christ among living believers. Finally, he outlines how the assembly serves both to proclaim and preserve the unified doctrine of Christ, upholding sacred truth as a display case safeguards precious treasures.
