What would you do with it?
I would start by making some serious changes in human society. For starters I would create a deadly virus, that kills within a few days and spreads like a wildfire. The virus would kill about 98% of the population. Only the few who are immune, survive. The empty cities and villages will be left abandoned to be taken back by the wilderness.
People live in small colonies around the world and communicate via the internet. ( Which basically becomes a free communication channel and information library, nothing more) They don't worship me as they worshiped their gods before, but I am known as a being of omnipotence and omnipresence, and they know if they do something I have forbidden, they must face my eternal wrath. Since I know all and see all, crime is pretty much nonexistent. Even those who are only held back by fear of me are vanquished. In the end people don't even think of crime. It will be a thing of the past, their will be no need of it.
I care for their needs and listen to their problems. If someone prays to me at night I listen. If someone cries out to me anywhere in the world, I am there for him. I cure the sick, and heal the wounded. I can do it, since I am a god. I have the power to attend to everyone at once.
I think I would be a good god. Where can I send my application?
