Yeshua defeated death. Therefor the death require in Torah, for example breaking Sabbath or adultery, is no longer needed because Yeshua covered this.
(I'm not saying I believe in stoning, this is just an example)
On stoning someone, say someone committed adultery, according to Torah they are to be stone.
Well for that stoning to happen, 1 the only person who can authorize this is the High Priest/Levitical Priests. There are none of those around today, so already in that, a stoning cannot be held in todays society. 2 there has to be at least 2 witnesses, no witnesses no stoning. 3 you have which kind of goes back to the witness side of things, you have to have an accuser, if there is noone to accuse it, no stoning.
We can see this in the story when the Pharisees came to Yeshua with the adulterer and they asked Yeshua what to do with her. His reply, "Let the one without sin cast the first stone." Slowly one by one the Pharisees left, therefor noone is left to accuse, there are no more witnesses. Yeshua forgives her, and tells her to turn from her ways.
So yes their is death in Torah, but to follow the death side of Torah would be to no accept what Yeshua did when He came and died for us.
I hope that explains it I guess
