If you have ever visited the Caribbean, you know that watching the sun rise in the morning or watching it set in the evening is a favorite pastime for the residents of Caribbean islands. They can tell the time of day by the length and location of their shadow. They know when a storm is about to begin by watching the length of the sun's rays. They also know when their harvest should be reaped based on the intensity of the sun.
In New Zealand, they have an affinity for the moon. They spend inordinate amounts of time watching the moon, mapping out the seasons based on the moon's characteristics, and determining weather patterns. Australians, however, love to stargaze. Sydney, Australia is well known for its love of the stars. Their observatories dot the city's landscape and attest to their affinity for the stars.
I suspect that in heaven, they also love the stars. Knowing that the stars are people in the universe who reflect the sun's light (Genesis 37:9-10), they watch as one star suddenly begins to twinkle and they know that the person is happy. They witness the sudden brilliance of a previously dim star and they know that the person experienced major repentance on a significant level. They see the distance the stars travel in the spirit realm and they know that the person is committed to growth and change. They also see when a star that seems too young to self-destruct suddenly explodes, and they know that the person has committed blasphemy, an unforgivable sin.
When an earthly star reaches a high level of purity, it no longer has a strong connection to earth and begins to turn its powers on itself. It sees itself as above the earth and must re-engage with the earth in order to remain grounded. It re-engages by taking on earthly tasks and channeling its powers into the completion of those tasks.
When a star reaches the brilliance of a sun, it no longer can interact closely with stars because it enables them to achieve a high state of brilliance, without the necessary learning process. Thus, the sun must retreat in order to enable the stars to develop their own brand of brilliance. When the stars reach their height of brilliance, the sun once again can begin to interact with them.
