There was a demonstration at the NO Intl Convention that addressed this in a way. There were 5 young brothers sitting around visualizing what they wanted in paradise. One wanted to live on a beach. Another wanted to live in the mountains. Another wanted his own 100 acre botanical gardens. One of the brothers asked how could they be sure that they would get these things? Wouldn't it be assigned. The botanical gardens brother said that was his desire and that the bible says Jehovah will satisfy all the desires of the heart, so he was sure Jehovah would give that to him.
So..... according to that demonstration, if you desire to be with your past mate, Jehovah will provide it. If you desire to watch unicorns humping dolphins, Jehovah will provide it. If you want your own panda petting paradise, Jehovah will provide it. If you want a dozen virgins to de-virginalize, Jehovah will provide it. Anything your heart desires........
