Eternal Life in the Kingdom. What are you suggesting they do believe in? Judaism is just the Old Testament. Talks about Heaven a lot in there. Only difference anybody could make here is that Christ says you must believe in Him to get there, Christ doesn’t come out saying that Jews go somewhere else. Christ WAS Jewish. All Christians are are followers of Judaism that believe Christ to be the Messiah whereas Jews don’t and believe the Messiah has yet to come and will be more like a warrior king like David was.
