Book excerpt: As Nehemiah rebuilt the walls of Jerusalem, Gashmu and the enemies of Israel mocked him: "It is reported among the heathen, and Gashmu saith it, that thou and the Jews think to rebel..." (Neh. 6:6). Too many Christians building communities today take the taunts of every modern-day Gashmu seriously. Community is a buzzword, and it turns out there's a lot of bad advice about how to build one. In Gashmu Saith It, Douglas Wilson includes forty years of experience for Christians wanting to build robust communities without retreat or compromise on the foundation of the Gospel. This book is full of wisdom: Get calluses. Be loyal. Fight sin. Build walls on the outside and a church in the middle.
