We are way, way too serious! I have been there also. I have since just not given a crap about much. It dose not mean I do not love and pray for justice and peace. It just means I am not letting it get to me. I have found through comedy that I have become a little less sensitive and much more mentally clear.
Does Christianity teach that we and the universe are one? I think that it does. Jesus said I and the father are one. If Jesus made us to be like him, one with the father than it is only to reason that we are apart of the whole not separate from creation. Enjoy!
