A lot of people, largely because of secular Jews portraying this lie, think that the Old Covenant and Judaism do not believe in the resurrection of the dead.
Nothing could be farther from the truth. Scripture makes it very clear that God promised to resurrect the dead and give new life. It is frequently repeated (rf. 2 Maccabees 7:22-3. 12:43-4, Ezekiel 37:12-3). Here are these passages looked at in depth.
“Therefore, since it is the Creator of the universe who shaped the beginning of humankind and brought about the origin of everything, he, in his mercy, will give you back both breath and life, because you now disregard yourselves for the sake of his law.” (2 Macabees 7:23)
“He then took up a collection among all his soldiers, amounting to two thousand silver drachmas, which he sent to Jerusalem to provide for an expiatory sacrifice. In doing this he acted in a very excellent and noble way, inasmuch as he had the resurrection in mind; for if he were not expecting the fallen to rise again, it would have been superfluous and foolish to pray for the dead.” (2 Macabees 12:43-4)
“Thus says the Lord GOD: Look! I am going to open your graves; I will make you come up out of your graves, my people, and bring you back to the land of Israel. You shall know that I am the LORD, when I open your graves and make you come up out of them, my people!” (Ezekiel 37:12-3)
In fact, the most highly revered rabbinical scholar Maimonides stated there are 13 fundamental beliefs a Jew must accept to be a Jew and one of them is the resurrection of the dead. Without faith in the resurrection one cannot be a Jew. Yet we are repeatedly told the lie that the belief in the resurrection is devoid of any basis in the Old Testament and comes straight from paganism.
Oddly enough I do not recall hearing of the resurrection in paganism. Gnosticism believes the soul is eternally separated from the body after death and Gnosticism is the pagan sect which rejects the Trinity for several deities. Ironically Gnosticism is the one that is popular today though hardly mentioned by name; you hear stuff about the spirit or the soul, but no the resurrection which is scoffed at. Yet, the neo-pagans claim the resurrection is of pagan origin yet they cannot bring up any concrete evidence that the ancient pagans believed in the resurrection of the dead as in having a risen and glorified body.
