Edward Boyd's agnosticism rested "not ... too much on any positive position ... but rather on a host of negative ones" about Christianity. In an attempt to address these negative issues, his son Greg, a professor of theology, asked his father, a strong-willed, highly intelligent, and stubborn 70-year-old, to enter into a correspondence in which "all of their cards would be laid on the table." Greg would give his father the opportunity to raise all his objections to the veracity of Christianity, and Greg would "answer these objections as well as give positive grounds for holding to the Christian faith." Three years and more than 30 letters later, Letters from a Skeptic was published and Edward Boyd came to accept Christ. During his journey, he and his son hash through such topics as why the world is so full of suffering; why an all-powerful God needs prayer; how you can believe in someone who rose from the dead; and how another man's death can pardon others. Despite their brutal honesty, both men exhibit respect and love toward one another as they address these volatile subjects.

It is unproductive to try to believe something beyond your grounds for believing it and dishonest to act as if you believe something more strongly than you do. Overbelief is not a virtue. For example, I am far from certain on many Christian beliefs I hold. I lean toward the view that the days of Genesis are vast periods of time and not literal twenty-four-hour periods. But about two days of the week I flip-flop and accept the literal view. Based on my study, I cannot convince myself either way... Other beliefs of mine have grown in certainty over the years?¢‚Ǩ‚Äùthat God really exists, for example. We should be honest with ourselves about the strength of our various beliefs and work on strengthening them by considering the issues relevant to their acceptance.

It is now some years since I detected how many are the false beliefs that I had from my earliest youth admitted as true, and how doubtful was everything I had since constructed on this basis, and from that time I was convinced that I must once for all seriously undertake to rid myself of all the opinions which I formerly accepted, and commence to build anew from the foundation...

Philosophy has been cultivated for many centuries by the best minds that have ever lived, and nevertheless no single thing is to be found in it which is not a subject of dispute, and in consequence which is not dubious...

We have to be continually reminded of what we believe. Neither this belief nor any other will automatically remain alive in the mind. It must be fed. And as a matter of fact, if you examined a hundred people who had lost their faith in Christianity, I wonder how many of them would turn out to have been reasoned out of it by honest argument? Do not most people simply drift away?
