Proof that the Greek Gods are real: They appear in dozens of stories that people were, at that time, convinced were right. Get the idea? Try as you might, you can't prove that god exists. That's why I'm a Psion. I can prove that Psionics exists. I can move small objects and influence people and occasionally see things before they happen, to name a few. If you're going to talk about faith and that sort of thing, then why are you also talking about proving things? It makes no sense.
On a related note, some x-ians have asked me to try believing in god for a while and see what happens. Would you guys ever try Psionics? I doubt it. Because you say it's a sin, right? But doesn't Jesus supposedly forgive you for all that?
The only people whom you are influencing are unbelievers of the Word of God!
And not only that, but the
god of this world has got you in the grip of his hands.
Jesus saith unto him, Thou hast said: nevertheless I say unto you, Hereafter shall ye see the Son of man sitting on the right hand of power, and coming in the clouds of heaven.
