So in the new system, will everyone's foreskin grow back??? Will Abraham and all his contemporaries be resurrected Circumcised or intact? Inquiring minds want to know.
The "new system" is a Jehovah's Witness fabrication. At least for Jews, there is no such thing. This present life may be all there is.
The Jewish sages and prophets did speak of what later Jewish teachers have come to call "Olam Ha Ba," the World to Come or "Afterlife." Whether or not this is literally true or to be expected we will have to see, therefore Jews do not live their present lives in expectation of it or center their hope and daily focus upon it.
Some Jews, therefore, see the idea of the resurrection as something that happens in the present life and not in Olam Ha Ba. For instance, when one changes their pattern of life from a set of unhealthy, self-centered, selfish living to one more healthy, giving, and healing, one can be said to be experiencing a "resurrection" to true life as God intends for us. For many Jews the idea of a physical resurrection is naive, childish, but for others some expect it in some form or another for the dead when the Messiah comes.
But details like what happens to circumcision marks are considered trivial. Since Jews have no definitive evidence regarding the nature of Olam Ha Ba, it does little good to speculate about exactly what it will be like for humans. How can one give an answer? Where does one get the information from? It has not been provided to Israel or to our prophets and teachers, therefore there is no answer to give, at least from the Jewish perspective.
Anyone else who gives an answer obviously claims to have tapped into the Divine. Thus make sure of their credentials before you accept what they offer you.
