I enjoyed a number of the points in this essay.
Dr. Jaco Gericke's Deconversion Story: "Autobiography of a 'Died-Again' Christian
<snippets>
It was a little late in the day, however, when I realised that studying theology can be a downright dangerous business for any believer. You go into it full of romanticised and naive ideas of what it is all about. You enter thinking you know quite a bit about the Bible, only to discover that you were grossly overestimating yourself on this matter. You expect to be spiritually fed, only to discover that all is not as it seems.
. . .
I used to hear stories of people who started their studies as Christians and left it as atheists. I used to laugh at those impossible fictions. After all, as a sound and orthodox reformed theologian, I genuinely believed in the endurance of the saints and the impossibility of a true Christian losing faith. Becoming an atheist was the last thing that could happen to me, a true Christian, especially from studying the Bible. It was simply a preposterous and inconceivable notion. But somewhere along the way something happened. Something went horribly and frighteningly wrong. Today I no longer laugh at those stories. To be sure, I have become a character in my own impossible horror story. I would like to cry but there is no more tears left to do so. Now I am not even post-modem. I am nothing. I cannot be labelled. I have no mentors. I have no heroes. All scholarship seems like a game without any capital T Truths, any real progress or telos.
