Sire concludes the book by mentioning that worldviews are not as voluminous as one might think, but many of them overlap each other in nuanced forms that make it appear there are numerous worldviews.
To choose an adequate worldview, Sire rightly points out the need for the following. First, humility is essential. We just don’t know everything so it’s important to come with that reality in mind. Second, there must be intellectual coherence where the laws of logic are rightly applied so falsehoods are avoided. Third, there must be experiential reality where the data of all reality is considered by what we know through critical analysis and scientific investigation. Fourth, there must be explanatory power where what is purported to be explained (e.g., human enigmas) are actually explained. Lastly, an adequate worldview must be subjectively satisfactory whose implications can be lived.
According to Sire, at the end of the day, a worldview can only satisfy if it’s true (Pg.198). Christianity, says Sire, meets the above mentioned criterions for choosing an adequate worldview and makes most sense of reality as we know it, even though it has its own problems. Christianity, is not merely intellectual as a worldview, but an encounter with a person—the risen Christ that makes the examined life worth living.
