You can never truley know for sure whether "God" is involved in your life or not. Most people would like to believe that "God" plays a large roll, but the important factor to consider here is whether or not it was "God" or just personal will, luck of the draw, or the most likely out come. Religion is used to explain the unexplainable or things we just flat out cant come up with an explination for. So in short you have to look at all the factors before jumping to the conclusion that "God" has made all that is good in your life and look at what YOU personaly have done to make a comfortable life for your self.
