This is the third volume in Alvin Plantinga's trilogy on the notion of warrant, which he defines as that which distinguishes
knowledge from true belief. In this volume, Plantinga examines warrant's role in theistic belief, tackling the questions of
whether it is rational, reasonable, justifiable, and warranted to accept Christian belief and whether there is something epistemically
unacceptable in doing so. He contends that Christian beliefs are warranted to the
extent that they are formed by properly
functioning cognitive faculties, thus, insofar as they are warranted, Christian beliefs are knowledge if they are true.
