Jews do not belive in Sin and Hell

Hare Krishna to all the devotees.
Please accept my Dandavat Pranam.

I was talking to a Jew, and he said Jews do not believe in Sin and Hell.
I would like to get some knowledge about Jews and how to preach them Krishna Consciousness philosophy.

if anyone can help me in this regard it will be a great service to Srila Prabhupada as we are trying to preach to a person so that he can become KC.

All Glories to Srila Prabhupada,
Your Servant
Krishna T
