The highest world of ultimate reality is personal and dynamic and in time - but eternal.
It consists of the Holy Trinity, and other persons such as angels and Men; and these exist in time (linear, sequential) - life is essentially a story, open ended, life is work: life is doing.
Life is about Love, and love is between persons and personages, and it is always growing and changing.
The lowest world of mortal reality on Earth is much the same; but temporally-bounded - it has a beginning with birth and an end with death; and the Earth itself and this world has a beginning and an end.
But in between there is a middle world of (apparently) static, blissful contemplation.
In the middle world there is no time - or, at least, no time is perceived by consciousness - so the middle world is eternal, but instantaneously eternal in contrast to the serial eternity of the highest world.
Instead, consciousness is aware of itself as unchanging and in the present moment only - with no past and no expectation of the future. It is a state of pure being.
In this middle world, Love is like being bathed in continuous and glorious light; and like beaming such light out from oneself.
We get glimpses of this - short segments of it, hardly noticed before gone - here on earth in ecstatic trances.
Our mortal life on Earth is inside the middle world, and the middle world is regarded as the highest world by many or most religions - for example Hinduism and Buddhism regard the middle world as highest.
Indeed, within Christianity - except for Mormonism, the highest reality of Heaven is conceptualized in terms of a type of middle world: Heaven is to dwell for eternity in the presence of God but in an essentially unchanging situation. God is understood to live outside of time and without change, with reality instantaneously available for His consideration and operation.
The idea (my notion) behind this is that God made this world for us to undergo spiritual progression (if we so chose) towards godhood ourselves, with the highest goal to go to the highest world, there to become 'grown up' Sons of God in a personal relationship with our creator as the highest goal - but all this is conditional upon our free agency.
As pre-mortal spirits, we chose to become incarnate mortal Men - and but being an incarnate mortal is full of contingencies; and for many people and much of the time, the highest hope is to lose our serial, time-bound selves in a state of static bliss.
The middle world is not the highest world, nor is static bliss the highest spiritual state - but theyare acceptable, permissable states - acceptable to God, permissable by God. We are allowed to stay in the middle world as long as we want to.
That is, Men are free not to recognize God as a person of the same kind as ourselves - nor to work towards a spiritual state in which we engage in a loving relationship with God (a relationship being in time and serial) - but instead to move into that static condition of pure but impersonal consciousness in the presence of God which is described above.
After a while in this state, we may begin to find it boring, or begin to feel sufficiently restored and re-energized after the exhaustion induced by incarnate mortality - then we may choose to move up to the higher level of Heaven, and to resume working on God's projects.
