If a person needs to see a relative, the angels will bring that relative. If the person really likes jewels, they will show the person jewels. We see what is necessary for our introduction into the spirit world, and those things are real, in the heavenly, the divine sense. They gradually educate us as spirit beings, and bring us into heaven. We grow and increase, and grow and increase, and shed the concerns, desires, and base animal stuff that we have been fighting much of our life.
Earthly appetites melt away.
It is no longer a struggle to fight them. We become who we truly are, which is part of the Divine. This happens to loving people, people who are good and love God. Only God knows what's in a person's heart. Someone whom we think is despicable, God might know as a wonderful person.
