The church is faced in the postmodern age by several distinct apologetic challenges. Internally, the church must defend the faith against ignorance, against compromise, against doctrinal apathy, and against denial. The church now suffers from a breathtaking deficit of doctrinal instruction and biblical truth. In some churches, the great truths of the Christian faith are unknown, and in others, these truths are left dormant and untaught. Beyond this, the very real dangers of doctrinal corrosion and heresy threaten.
