The World to Come is the dimension of ultimate reward and closeness to G-d. It is the ultimate future when the period of testing for mankind will come to a close and the very concept of evil will no longer be necessary. At that time, G-d will rectify evil itself and return it to its root. The king will then invite the hired temptress into his palace, telling her, "You have done your job; now you can get your reward as well." The realm of evil will then be completely transformed and included in holiness.
