Debate fuels my Fire
Sorry, you're wrong. There is a section that I'll quote;Umm, no it doesn't? See, this is why I have such a tough time with these arguments. Folks are just making stuff up to support their points rather than actually LOOKING at what's there. I mean, THIS is the relevant part of GoS:
