Christian apologetics should never be restricted to guarding against attack. We have a responsibility to communicate the gospel to our generation. Christian apologetics is not like living in a castle with the drawbridge up and occasionally tossing a stone over the walls. It is not to be based on a citadel mentality- sitting inside and saying, “You cannot reach me here.” If the Christian adopts this attitude, either in theory or in practice, his contacts with those who have accepted twentieth-century thought will stop. Apologetics should not be merely an academic subject, a new kind of scholasticism. It should be thought out and practiced in the rough and tumble of living contact with the present generation. Thus, the Christian should not be interested only in presenting a nicely balanced system on its own, like some Greek metaphysical system, but rather in something, which has constant contact with reality- the reality of the questions being asked by his own and the next generation. — Francis Schaeffer (from, The God Who is There)
