To What Does It All Come Down?

Many are the thoughts through my mind tonight.  I believe it started with the somber acceptance of the belief that I am most depraved.  The rest of the thoughts came out as a sort of make-believe conversation with a friend of mine whom I only met recently.  The question came up concerning the necessity of the cross.  Rather, the necessity of the cross became more prevalent as I became more aware of my nature.  The more depraved I realized I was, the greater my need for the cross.  I somehow tied these thoughts into the question of certainty and its varying degrees.  I'm fascinated still by the Cartesian problem, namely the question, "What is real?"  How do we know what reality is?  How can we be certain of that reality?  Well, it depends on how certain you want to be.  The ultimate answer is that everything takes some degree of faith.  There is no guaranteed, hard-evidence proof of anything, save maybe that we exist in some state or form.  Frege's failure also points to this end.  Judging by everything to which I have currently been exposed, I'm starting to feel like everything in life must be taken by some measure of faith.
