I’m going to skip ahead just a bit in my outline of the evidence against Christianity and give a brief overview of the matter of world versus worldview, relative to the Myth Hypothesis versus the Gospel Hypothesis. One of the consequences of the Myth Hypothesis is that, since God does not exist in the real world, He is restricted to “existing” within a particular worldview—that is, within a particular individual’s subjective perception and interpretation of reality. This in turn produces a number of related consequences, because of the inevitable conflict between the believer’s worldview, in which God does exist, and the real world, in which He does not.
One of those consequences is the perpetual friction between world and worldview. Believers will feel pressure on their worldview because their dealings with reality will continually confront them with facts that are inconsistent with their beliefs, producing friction and even erosion of the Christian worldview. This in turn will produce the need to find some way to counteract the erosive effects of contact with the world and reinforce the worldview. Believers will experience a need to take their faith in for frequent “scheduled maintenance” by meeting together to encourage one another in the faith, and to exhort and admonish one another. Unmaintained faith will tend to weaken over time, and produce backsliding.
They will also need to actively defend their worldview in the broader arena of cultural perception. And once again, the Myth Hypothesis imposes distinctive restrictions on the form this defense will be able to take. They won’t be able to reinforce their worldview by pointing to how God Himself shows up in the real world, because His non-existence will prevent Him from showing up. They won’t be able to provide verifiable, objective, real-world evidence consistent with their worldview, because the chief difference between world and worldview will be the fact that God only exists in the latter. Consequently, their worldview defense will need to resort to techniques that have less to do with science, and more to do with politics and indoctrination in the beliefs and worldviews of men.
