It has never mattered to me whether this force for Good is real.
The goodness is the only point.
I'm here because I hate evil.
Prince Philip, 1988: "In the event that I am reincarnated, I would like to return as a deadly virus, to contribute something to solving overpopulation."
The other day Q said, "now comes the pain".
That pain is Truth; evil loathes the truth. Goodness is untouched by Truth, and loves its purity.
