"It is helpful to distinguish between negative and positive apologetics. In negative apologetics, the major objective is producing answers to challenges to religious faith. The proper tack of negative apologetics is removing obstacles to belief... In negative apologetics, the apologist is playing defense. In positive apologetics, the apologist begins to play offense. It is one thing to show (or attempt to show) that assorted arguments against religious faith are weak or unsound; it is a rather different task to offer people reasons why they should believe. The latter is the task of positive apologetics."
