There's nothing wrong with that, to have doubts, and of course focusing your mind like a laser isn't easy for anybody who is untrained. Lifting a 200 pound weight is pretty hard for most people. Things like telekinesis, communicating with the Gods telepathically e.t.c. is comparable with trying to lift a 200 pound weight. You've got to train yourself to do that obviously. But you can know Satan and the Gods are real with some practice. Or when you're new with minor signs and coincidences (you've got to be observant for those though).
But...Wait a minute! You DEDICATED yourself while you were not sure that Satan and the Gods aren't real? That means you lied during the dedication ritual and it didn't work because you didn't mean it. Seriously, don't make that mistake again and say things you don't mean to Satan. They don't pay attention as much to your words as to what you mean behind them. The dedication ritual says
<[/IMG]Before the almighty and ineffable God Satan/Lucifer and in the presence of all Demons of Hell, who are the True and the Original gods, I, (state your full name) renounce any and all past allegiances.[/I]
Obviously if you aren't sure Satan and the Gods are real it means you lied during the above part.
