Heavenly bodies are 'the Angels' who, through their constant movements, changes and control every thing on earth.
For example, every human is conceived, only through the grace of the Moon's movement in the heavens.
There are short moment to moment cycles and longer millennium to millennium (and even much greater) cycles.
We are focused on a 2 millennium cycle. 2000 odd years ago Jesus said, the kingdom of God is close at hand. This was Jesus' lingo. And for Jesus it was a literal statement. Fact is, a thousand human/earth days is but one day for Jesus.
2 Peter: 3 King James Version (KJV)
8 But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day.
2000 odd years ago, Jesus knew that in two of his days (i.e. 2000 earth years) the planets etc. will realign to empower His Spirit on the surface of earth. The Spiritual Age of Aquarius is at hand. Equinoxes and Solstices are in their homes. The Spirit of Jesus is enhanced and empowered.
Jesus' Spirit is Christ consciousness. It is also the Spirit of Truth/Spirit of Intercession/Spirit of Love.
Two of Jesus' days have passed since His crucifixion on earth, the heavenly bodies have aligned appropriately and His Spirit is now boss and ruler on earth. The kingdom of God that was close at hand, two of Jesus' days ago, has become the kingdom of God is now at hand.
The question is are you actualized and relevant so as to be counted by Him.
Matthew 7:21-23King James Version (KJV)
21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
Did you do the will of God? Did you bring forth fruits onto God (children of God) or did you bring forth fruits on to death (children of the flesh).
The will of God is to fill the surface of earth with only children of God, like Isaac and no children of the flesh, like Ishmael. Not all of Abraham's generation are chosen.
Galatians: 4 KJV N.T.
22 For it is written, that Abraham had two sons, the one by a bondmaid, the other by a freewoman.
23 But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise.
30 Nevertheless what saith the scripture? Cast out the bondwoman and her son (Ishmael): for the son of the bondwoman (Ishmael) shall not be heir with the son of the freewoman (Isaac).
Did you do your part. Did you cooperate with and contribute to, God's agenda. Did you bring forth only children of God and no children of the flesh?
Did you know that when you transgress the ten commandments (i.e. when you covet) so as to have procreative sex out of an expression of spirit/love, you bring forth only children of God (like Isaac)?
However if you have procreative according to the ten commandments, you bring forth only children of the flesh (like Ishmael).
People like Isaac will inherit, God's kingdom of heaven on the surface of earth. People like Ishmael will be cast out:
Galatians: 4 KJV N.T.
30 Nevertheless what saith the scripture? Cast out the bondwoman and her son (Ishmael): for the son of the bondwoman (Ishmael) shall not be heir with the son of the freewoman (Isaac).
People like Isaac are spirit and Spirit/N.T./Christ actualized and based. They look to things that are 'not seen' and eternal.
People like Ishmael are physically, Mosaic/O.T. and ten commandments based. They are not spiritually actualized. They look only to things that are 'seen' and temporal.
The above is the Christian position.
