Time in A Genie
Examining the end of days then marking them on modern calendars is patronising the house of demons. Reading numbers in scripture and using those to predict dates is Satan's trap for the arrogant. Formulas for predicting biblical times are a fallacy.
The Israelites means of tracking time commenced from the moment they left Egypt. It was on a lunar day basis. Each day commencing at evening monitoring moonrise. Each new month, day one, was noted with its moon event. The repetition of this calendar is 689,472 years.* There is indeed an object lesson here; no two days were ever to be alike between years. The cycle of repetition is incalculable in man's puny lifetime. The puny lifetime is Satan's gift.
The marking of days happened by observation. What is the object lesson? One day to the next marking moonrise on the horizon, the moonrise is not an identical event between any two places on the earth. This is because of the earth's natural gyration on its orbital axis. If the true God had wanted a precise marking of time the Israelites would have had it. Time has always been the true God's dimension.
Why give the Israelites a lunar day marker? Women follow a lunar cycle for menses, shedding of the uterine lining of thickened blood. Blood is sin. The Israelites God reminded with the moon that their days of sin were going to be forgiven and they would be saved by means of a woman, the firstborn of creation. She came to earth as the son of man.
What about the practice of creating formulas for predicting future dates using biblical events and what for all intents and purposes reads like a biblical equation, i.e. a day to the true God is one thousand years to a man? (Watch God say, "What a bunch of crap!" In the days of Israel a scale was used for commodities not counting, unless it was people. So linear, additive, formulas applied to anything other than chattels is nebulous ground.) A day to the true God is also when He spent billions of (our) solar years mapping the planets and stars, and, then, casting them into orbit with a toss of His hand. And do not forget He used the womb of creation for this. Then He laboured over their composition of matter. (mac is not allowed to edit their to there. God says, "Leave it.") The orbit of the earth around its axis, (an earth secular day) has meaning only if you are confined to the earth in some way.
We need to sleep. The moon is a useful luminary for sleep. That said we do not want to fall asleep in death -- sin's wage. The unfortunate reality: we live with a death sentence. Again, Satan's gift. Life only comes from being remembered in the true God's book of life. Get ye in that book.
