What happened to radical Christianity, the un-nice brand of Christianity that turned the world upside-down? What happened to the category-smashing, life-threatening, anti-institutional gospel that spread through the first century like wildfire and was considered (by those in power) dangerous? What happened to the kind of Christians whose hearts were on fire, who had no fear, who spoke the truth no matter what the consequence, who made the world uncomfortable, who were willing to follow Jesus wherever He went? What happened to the kind of Christians who were filled with passion and gratitude, and who every day were unable to get over the grace of God?
