I got into a debate one time with a Christian guy about jesus as god in the flesh. He didnt waste his time with the typical proof texts and such because most of that has been changed in new world translation. He showed me how the new testament referances the old testament and what the authors were talking about. Especially the direct references to word of the lord in the old testament. It was pretty straight foward. I even doubled checked it against secular sources like Bart Erham and it was pretty much the same.
Now you can question the legitimacy of the bible but you really question the authors intent.
Then i tried to pin down my beliefs as a witness (unbaptised). I then realized that i didn't have any. I could'nt pin down any tenets of my faith. All i did was go door to door with a briefcase full of books playing silly bugger full of ridiculous circular nonsense that i didnt understand.
Then i realized no on understood it. Doctors, engineers, lawyers. We are all the same.
It scares me.
