The short answer, of course, is that I was blessed to have been brought up that way. I have always felt God's guiding hand on my shoulder. I have always lived in His presence, and known the peace of mind and the exaltation that brings. But when you grow to man's estate, and it is obvious that what you were taught is rejected by many, it behoves you to determine whether it can be justified intellectually as well as experientially.
For myself, my degrees were in science, with particular emphasis on zoology. But over the decades I have sought to satisfy my curiosity about such fields as history, anthropology, and psychology. A cynic once declared that I have read widely, but not deeply. By that as it may, it provides an advantage over those whose studies have been intense in a single field and limited in others. It has always appeared incongruous to me that any educated person could be a non-believer - especially if his field is astronomy or ancient history, when he must face the issues head on.
