Why can't it just be because? The land flooded because it rained. The person got cancer because they smoked, the family died because they were hit by a drunk driver? The man who killed several children has a mental disorder.
If you throw a coin into the air and 60% of the time it's heads and 40% is tails is it God's will or just because?
Every people that have ever lived on this planet have prayed or worshipped some form of a God or Gods. The sun, moon, rain and on and on it goes. I believe it's because we are puny compared to this vast planet, this never ending universe and we seek answers. Why did my child die, why did the crop fail, why am I in pain? We don't know the answer so we invent a God or Gods to blame, support or fill us in on the questions that haunt us. We seek light when it's dark we seek answers when we have none, we seek comfort in our sorrow and pain and so we invent a God to help us. That is what the Indians did, the Incas, the Eyptians and every culture that has ever lived on this planet.
Perhaps instead of looking to a God or a Buddah or a Moon Goodess we should just look inside of ourselves and find the answers. How can I be a better person? Why isn't that enough?
