Having read all of that and watched parts 1 and 2 of the video, I find it rather odd.
You can say the animal "submits to the will of god", but in reality you're just being 'nice to it' before you hold it down and cut its throat. Telling yourself god has anything to do with it just because you fancy a lamb chop is a bit silly to say the least.
Is there some concrete evidence that it doesn't feel anything, the sheep seemed to die quickly but it struggled at first. I suppose a few seconds of pain could be considered okay depending on your view.
