This excerpt is taken from an article entitled "The Children's Crusade" in the devotional, Tabletalk.
"We seek His kingdom as we seek His righteousness. The world is preserved, and the boundaries of the kingdom expand when we live as His children in simple, trusting obedience. The world is changed by changing diapers, by hugging wives, by doing chores diligently, and by singing joyfully. war is fought by peaceful countenances. Loyalty makes walls come tumbling down. We do not, as the crusaders did, leave our hearths and homes, our wives and children, cross land and sea, and hack and poke with sword and spear. We instead cross the room, pray blessing on our children, and dance with our wives. We sit at the table, eating the fat of the land, talking about the glory of His provision in all our days. We visit the orphan and the widow. We preach the Word in season and out. We break bread and we drink the cup. And the Serpent trembles in his bunker."
