If I were God I would want people to know about me. Either I spoke to and encouraged people or, if recalcitrant, punished them a bit (a few thunderbolts). I answered this before and it wiggled and I lost it all (better than what follows). A kind god gives rules and so on, but understands when someone doesn't know the rules, explains (through others).
A feeling of my presence would surround all those who are working to spread understanding of my existence and they would spread it to others. Rather lost my thread, but there you are. :)
Seriously
