PREDESTINATION, what it means?

To understand what it means, we have to look first at the reason why the ancient world had an inherent interest in the cosmic language. First of all they understood the balance that coexisted in the forces or entities governing the laws of energies and the consequences in the event that chaos, personified in the forces of darkness, were in control. One of the first things that ancient civilizations wanted to do was to ensure a coherent society, and the harvesting and planting of crops, through the establishment of an accurate calendar of cosmic events.
Most of the early calendars were lunar "monthly" calendars, but slipped the seasonal "planting" year by 11 days. It means that any unbalance produced in that braked of time were against the ancient rulers who had a clear control and understanding how this cosmic language worked. It sounded like the end of a civilization, or the end of a kingdom, and so on. No land to continue 'planting' the seeds of their rule.
Predestination is the teaching that GOD has, from all eternity, freely determined whatsoever shall come to pass. We find this in the Scriptures in the Book of Ephesians, chapter 1, ".... having been predestined according to His purpose ..."
We can see His plan when on May 28, 585 BC, the earliest sun eclipse recorded as being known in advance of its occurrence, happened at the Battle of Halys.
The civilizations involved in the conflict were the Hittites and the Medes. The two were crucial in the development of Israel.
The Kizilirmak (Turkish for "Red River") or Halys (name in Ancient Greek), is the longest River in Turkey among the Rivers which originate and end in Turkey. Generally speaking it symbolizes the world power that come and goes between civilizations. This was the place where the solar eclipse took place. The conflict was interfering with the predestination of events that had to take place in order to continue GOD's plan. Hittites and Medes, who were God fearers, immediately stopped the war and agreed to marry the forces of destiny through their own children. Cyrus the Great, ruler of Persia's Achaemenid Empire came as a descendand of that specific union of powers.
GOD showed his immense power through the solar eclipse to these powerful civilizations and they understood the meaning, they, instead of continue the war and blocking the power, they resolved in letting peace to work the destiny.
