if the supernatural does exist. what's with all the secrecy? out of all of the gods "known" to man throughout history, not a single one has made his actual existence known. never did a sky daddy come down to show himself to everyone... why?? why does god not make his existence known, and then let everyone decide whether or not they would like to worship him for eternity??? why turn it into a silly game of hide and seek, where only some humans claim that the gods have revealed themselves to them, while others are left in the dark....... why not just make his existence known and let us make the decision whether or not to follow him.... we will still have free will of course....
Read as many books on the subject as you can get hold of. Look for different viewpoints, different religions and different methods, don't just look at the most popular, obvious or easily refuted god concepts.
Perform invocations, create sigils in your own blood, push your body and mind, sell your soul, sleep overnight in a cemetery. Work hard in your search.
Don't imagine that the gods are interested in you, don't think that they want your worship, don't believe that they'll look for you and most importantly don't imagine that they give a damn what you think.
If you aren't marked by the gods, don't expect it to be easy to find them and don't presume it matters to them if you do. That's my opinion on the matter. If you want to find a god, good luck to you, but don't expect it to be easy.
