Abstract

In part one of this book I argue for the conditional claim that if Christianity has at least a 50% epistemic probability, then it is rational to commit to living a Christian life (and irrational not to). This claim is supported by a contemporary version of Pascal's wager. In part two, I then proceed to argue that Christianity does have at least a 50% epistemic probability, by advancing versions of the cosmological argument, the fine-tuning argument, and historical arguments for the plausibility of the resurrection (along with a few other relevant considerations). Assessments of the problem of evil and divine hiddenness are also given. Finally, in part three, I discuss the lives of three Christians from the 20th century (Dietrich Bonhoeffer, Jean Vanier, and Immaculee Ilibagiza) in an effort to illustrate how a life of Christian commitment is not just reasonable, but worth desiring as well--satisfying both the head and the heart.
