That purpose is already known to our higher self. Nothing can happen in the universe before it's time. Everything in the universe is intimately connected. For example, the beating of a single butterfly's wings in China affects the weather in America in some way. Other worlds with intelligent life exist in the universe similar to our own.
Souls inhabit the planets of our solar system.
Our solar system is united by a transparent net, or web, and each thread shines with great radiance in the spirit realm. The universe is filled with life on other planets. There are many universes and God has authority over them all. Spiritual reality is the true reality of which physical reality is only a shadow. They whisper things to us to help us to do what is right because of their great love for us.
