I've opened the door twice to Jehovah Witnesses before. The first time I was at bit naive and didn't know anything about them, but also I'm just too polite to tell them to go away, so I took the Watchtower mag they offered me. I read it, and its a load of shit. But to be honest even before reading I knew it wasn't going to convert me, I had already realized God was as real as Santa and the Easter bunny many many years before. The same woman came knocking a couple weeks later, my mum answers the door, and the woman asks to speak to me 'the nice young man that lives in this house', lol I was wearing a lamb of God t-shirt when I opened the door to them and took the Watchtower.
The second time this young guy comes knocking, he opened up one of the magazines and pointed to a picture of a family in some park flying a kite. It was all picturesque. He asked me "do you think we will all live like this and be happy?" and I said "No, because humans have a predisposition to fight one another." he and turned and left.
A few months back I was walking to the shops, and this guy was handing out leaflets. I took one, and looked at it, it said "how do you plead before God" and I turned round and said "I'm sorry, what?"
So I was speaking to this guy for about 45 minutes, listening to him. He's a mathematician, and he believes the universe was created in 6 days and that carbon dating is inaccurate, wtf, a man of science that is illogical. So I said well from my education I've been taught to create hypotheses, do tests, collect evidence and come to a conclusion. I said to him, I prefer science because it changes. Sometimes somebody will come along and say, actually I've created an experiment that shows what we originally thought about the blah blah blah is infact incorrect, it actually does blah blah blah. The experiment is repeated and the same result is produced, the scientist gets a nobel prize. But if I say to a group church goers, actually I'll prove we have all evolved from a common ancestor, they'll metaphorically burn me at the stake for being a heretic. Then I said to him, haven't you heard the news, they've found the fossil remains of the common ancestor that links all monkeys and prime apes including humans. They found it in Germany.
As for judging me, if there is a God, I'll say to him, hey I haven't done anything horrible during the course of my life. And whats the deal with Catholics, you just confess your sins and accept Jesus as your saviour and then you go to heaven. Right, so a murderer and pedophile can find Jesus while they are in prison. Are you saying I'm not going to get let into heaven but the murderer and pedophile will be. Yeah, where's the logic in that.
