Faith

I don't understand it.  I know that faith is an important piece of the puzzle in life.  But why would God make the world the way it is and then expect us to have faith.  How can we believe in something we do not see?    I mean all I really get is that we sinned and somehow the results and ugliness in the world are because of sin?  It makes sense but it doesn't provide the suffering any relief other than the problem.  I have been told multiple times that the answer is Jesus Christ.  Understandable, he is my savior, but that doesn't take away the present sufferings we endure.  It seems we are placed into this existence whether we like it or not, it is our duty to endure.  I am still lacking proper perspective on things.  But what is someone supposed to do with it?   And WHY do I have this constant nagging within me on the way how things 'should' be.  Why do I keep constantly finding fault in everything and everyone?  I'm f*cking the one who is flawed yet I somehow project it on to other people.  I cannot see reality at all, It's dimmed and frustrating.
