How can I prove that my God exist? I can't. I can only show by my outer actions that I believe in a higher force in my life. My action speak much louder than words, because what comes out of our mouths can be false. We have to believe in something or I don't believe that we can be human. The has to be something to make each day brighter than the one before, or we would give up all hope for a tomorrow. This is my causal argument, that things are cause and effect. Treat the world unkindly and you will be treated unkindly. I don't believe in just one God, because your beliefs are not just like me, and I can't see inside you heart or head. I can only believe in the actions you show that you believe in a higher being and that you believe that you may be held accountable on day.
