Is what you believe consistent with itself?

A 'worldview' is pretty much the lenses through which a person interprets reality. It's the big 'grand story' that explains everything in reality.

Christianity is a worldview.
Naturalism is a worldview. It says that everything that exists and that happens can be explained through observable, natural causes. It thus denies the existence of anything immaterial or spiritual.
Postmodernism is a worldview. It says that truth cannot be known, and therefore to judge anyone's worldview as false is impossible.
Nihilism is a worldview. It says that there's no meaning in anything. It's atheistic. It says that morality doesn't exist. It leads to despair, for beauty, meaning, morality are all subjective and ultimately pointless.

There are only two worldviews that are consistent with themsleves. Christianity and Nihilism.
