But whatever will happen will happen regardless of what anybody wills except in one case. There are those who believe that the way to live is to accept whatever happens as what will happen and if you want call it God's will because if there are reasons for things happening as they happen that have nothing to do with human will they will happen the same if it's God's will or if it is not.
The only thing open to change is personal attitude.
