Understanding worldview is a bit like trying to see the lens of one’s own eye. We do not ordinarily see our own worldview, but we see everything else by looking through it. Put simply, our worldview is the window by which we view the world, and decide, often subconsciously, what is real and important, or unreal and unimportant.
