Reasonable Faith

William Lane Craig's Reasonable Faith presents a systematic defense of Christian theism through philosophical argumentation and historical evidence. Writing within the evangelical Protestant tradition while employing analytic philosophical methods, Craig constructs a cumulative case for the rationality of Christian belief that engages both classical natural theology and contemporary apologetics.

The work advances four principal arguments for God's existence. Craig reformulates the kalam cosmological argument, contending that the universe's beginning requires a personal, transcendent cause. His presentation draws on both philosophical reasoning about actual infinities and scientific evidence from Big Bang cosmology. The teleological argument receives updated treatment through fine-tuning considerations, where Craig marshals evidence from physics and cosmology to argue that the universe's life-permitting constants demand intelligent design. The moral argument proceeds from the objectivity of moral values and duties to their necessary grounding in God. Craig's axiological approach maintains that atheistic frameworks cannot adequately account for binding moral obligations or intrinsic human worth.

Beyond natural theology, Craig defends the historical reliability of the New Testament accounts, particularly focusing on Jesus's resurrection. He employs criteria from historical methodology to argue that the resurrection represents the best explanation for the accepted facts surrounding Jesus's death and the early Christian movement's origins. This historical component distinguishes Craig's project from purely philosophical approaches to theism.

The work systematically addresses major objections to theism, including the problem of evil, divine hiddenness, and alleged incoherence in the concept of God. Craig's responses typically involve distinguishing between logical and evidential versions of these objections while offering defeaters for each. His treatment of biblical difficulties and apparent contradictions reflects his commitment to defending not merely generic theism but specifically Christian doctrine.

Craig's synthesis proves influential in contemporary philosophy of religion and popular apologetics. His rigorous philosophical argumentation combined with accessible presentation establishes a model for public religious discourse. The work's impact extends beyond academic philosophy into pastoral training and lay education. Critics challenge Craig's philosophical premises, particularly regarding causation and infinity, and his historical methodology, especially concerning miracle claims. Nevertheless, Reasonable Faith remains a touchstone for philosophical defenses of Christian theism, demonstrating how traditional apologetic concerns can be addressed using contemporary analytic tools while maintaining evangelical theological commitments.
