"I am struck by the absence of resistance, dissent, and critical judgment in the moral repertoire of contemporary evangelicals. These disciplines - and let us call them disciplines - are rarely intoned in our sermons, publications, and seminaries, and when they are, they are most commonly regarded as manifestations of pride. Evangelicals are quick to admonish unity when there is a whiff of disagreement in the air. Dissent must be quashed for the sake of harmonious ideals, which we consider spiritual virtues. But perhaps the situation only masks our swift retreat from the costs of discipleship, fueled by an inferiority complex, which plagues us ... We are failing to raise up a generation of Christian critics at a time when dissent should be a vital part of confessing Jesus Christ as Lord."
