Whether or not Satan exists really does not depend on whether you believe it or not..

You can't literally see the wind either, but you can feel and see its effects..you wouldn't deny that the wind doesn't exist, would you?

Satan has no reason to "reveal" himself to you or anyone else. That would defeat his purpose.

You know what evil is..you can see it's effects..you can feel it's effects, so evil is real..what is evil and where did it come from?? Satan of course..there is enough evidence out there to pretty much prove it without having to actually see a physical manifestation...and if you did, it likely would not be what you would expect.

Sorry, but he's real..believe it or not, it doesn't matter, only it would be better for you to have your eyes open and not have the wool pulled over your eyes.

That requires effort..and yes, you have to separate the truth from the nonsense..you will find both here and elsewhere as well.
