The entire concept of “eternal damnation,” “hell” and all of that nonsense were quite late chr-stian inventions which were literally stolen from Zoroastrianism and Mithraism. Even the word “hell” itself was stolen from Norse Mythology, which Rome did not even have any form of contact with until at the very least the Sixth Century CE, and more likely a couple of centuries after that. The Roman ch-rch was burning people alive on an everyday basis for not accepting chr-stianity long before they concocted the idea of eternal fiery torment.
Because there continued to be so many people that did not want to conform to their rule, they took it a step further. Every time a “heretic” was burned at the stake they would tell the entire crowd of spectators that this is what to expect for all eternity if they did not follow the “ch-rch.”
Nothing about chr-stianity has ever been believed or accepted by Judaism, and Judaism has existed for roughly 1,500 years before chr-stianity allegedly began, and closer to 1,900 years before it was really invented.
The chr-stian concepts of “heaven” and “hell” are pagan in origin, and the very thought of such things are expressly forbidden by the God of Israel.
