"I believe Christianity is true, but I could be wrong." Is this something a Christian should ever say? Adam has often said it, and Francis Schaeffer did as well, but what do they mean by it? In short, it's a way of communicating that our belief in Christianity is the type of thing that can be right or wrong. People need to understand that Christianity is a propositional belief system that can be objectively true or false. It's not just a subjective feeling or personal preference that's helpful or meaningful to me. In the end, Christianity either corresponds to reality or it does not.
