I got an invitation.
But I didn’t believe it.
I don’t believe you got an invitation.
Can you prove that you don’t believe it?
It’s impossible to prove absolutely that a person believes or disbelieves anything, but unless there is compelling evidence to the contrary most people accept a person’s word about their beliefs. I am sure Spiritus believes sincerely that he got an invitation, but his subjective testimony on this subject is not reason enough for me to believe in his invitation.
I don’t believe in invitations.
Yer pal,
Satan

“Atheists disbelieve through an inner conviction implanted by the absence of God speaking in their hearts.” 
I kid you not, I once ran across an atheist who claimed that God spoke to him and told him He didn’t exist. Honest-to-god-true.
But I didn’t believe him.
I do not blame you for your skepticism. I, myself, was incredulous at first. It was only a few moments ago, while reading Necros’ post, that I acheived my breakthough.
Necros, thank you, you have tought me that the invitation comes to all, but only when your heart is open can you receive it.
Gaudere, I know that you have received an invitation, too. You simply RSVP in your own way.
