This article addresses the title's question by first examining its presuppositions, and indicating that being afraid is not an inherent trait of being Reformed, and that the Reformed are not second to sectarians in Bible knowledge, as the latter do not have real Bible knowledge. Yet the author does identify that often, we as Reformed churches lack an integrated system of training in the truth, which manifests itself in the level of knowledge among professing members, impacting evangelism. The author ends by explaining that in many cases, a lack of knowledge is a proof of a lack of love, in which case fear can be great.
