I see two reasons that I would Credit God:
1. It is so much easier than being responsible for situations that I do not understand, good or bad.
2. If God is All powerful, All kowing, and Everywhere than yeah, it would make sense to credit God with all activity. There would be no free wil and we would have no choice but to credit God.
There would be no tragedy, just God's will. There would be no failure, just God's plan and we are the actors. See that sounds much better. Less thinking today, I do not want a headache of thinking about all the reasons why things are the way they are in life. I want to blame God like many others some days. The only thing that prevents me from joining the others is I have to be responsible for my own spiritual path. This is what self realization is about.
I wish you the best.
