Is there purpose in our lives?

As we read through The Stranger in English class, deep questions are asked. The Stranger presents a view of the world that contains significantly less purpose than other worldviews. Which begs the question: is there really any purpose in this world?

Quick summary of purpose in The Stranger (or at least how I interpret it): It's absurdist in the sense that there no inherent purpose in anything, especially things like the abstract and God. It's an existentialist perspective in that Meursault gives meaning only to physical things. Things that aren't given any purpose by Meursault have no purpose to him, thus resulting in his completely indifferent nature to other people.

As a society, we tend not to think like Meursault, or at least we don't think we do. Most people seem to believe in purpose in one way or another. As a Christian, my belief in God's purpose would oppose an existentialist viewpoint entirely. Others find purpose in one way or another, which may or may not fit an existentialist view depending on the person. From my point of view, there is purpose in everything, so existentialism, although interesting, isn't really for me. It's got some valid points, and maybe I'd like it a bit more if I wasn't religious, but it's something that I reject for myself. Maybe it's just more convenient for me this way, but I like to think that there is a purpose in everything. Thinking that way keeps my mood up when things don't look too good, even if it's beyond reason.

I mean, how else am I able to keep supporting the Lions?
