I thought this was really good I learnt a huge amount about epistemology, justification of knowledge and rationality. There are parts where it's sometimes a challenge to read but its very well written and worth the effort. Plantinga has mastered a huge amount of complex material and communicates this very well.
A powerfully argued defense of Christian faith - which is both true to the experience of most believers, and draws on a persuasive (and independent) theory of knowledge. Plantinga avoids the paradoxical use of reason to justify unreason, and presents a welcome correction to the unthinking verbiage of much modern theology.
