Any Gentile who accepts these Seven Noahide Commandments, and is careful to observe them, is truly a pious individual of the nations of the world, and merits an eternal portion in the future World to Come. (And with this merit, the person will be included in the Resurrection of the Dead). This applies only if he accepts them and does them because the Holy One, blessed be He, commanded them in the Torah, and made it known through Moses our teacher, that the Children of Noah were previously commanded to fulfill them.
Note that Rabbi Schochet taught that without the body your soul cannot do a damn thing.
There is no way in this world to accurately grasp and comprehend the ultimate good that the soul will experience in the World to Come. We only know the good we can experience now, and that is what we desire. In contrast, the future ultimate good is overwhelmingly great and cannot be compared to the good of this world, except in a
metaphoric sense. Nevertheless, this concept can be somewhat understood through the parable of the various types of pleasures that a person can receive in the present physical world. One can receive physical pleasure on a base level from eating tasty food, and on a more refined level from hearing good music. One can receive intellectual pleasure from understanding a deep insight. A soulful pleasure can be experienced from doing a favor for another person, and seeing that person receive pleasure from the favor. Many other things in this world can give a person various levels of pleasure. Those pleasures that are felt by a person's senses, such as the taste of food, cannot reach the level of pleasure that one can receive from the higher human faculties, such as comprehension and happiness. The more refined the faculty, the greater and more uplifted is the pleasure it can receive.
