In Hebrews 11:3 we read: “By faith we understand that the worlds were framed by the word of God, so that the things which are seen were not made of things which are visible.” – “the worlds” is a translation of the Hellenic word “aiones” also known in English as “aeons“, also rendered as “ages” elsewhere in the Bible, e.g.
Matthew 12:32 “Anyone who speaks a word against the Son of Man, it will be forgiven him; but whoever speaks against the Holy Spirit, it will not be forgiven him, either in this age or in the age to come.
So God did not just create the general construct of Time, but more specifically He also created the “ages” – which are chronological epochs along the overall construct of Time, which are of different spiritual dimension, in which God wrapped the particular work that He wanted to do on Earth during that particular “age” (“aion”, “aeon”).
E.g. we know there was an ‘age’, or perhaps ‘ages’, of which we know very little, preceding the times of normal humans as we understand humanity in our days (e.g. people lived hundreds of years, some were offspring of angels with humans, etc).
Here is a portion of what we know for sure from the Bible, from God’s perspective; leaving aside the age(s) before and after Noah, there was the ‘age’ before the Law was given to Moses. That is when God made a covenant with Abraham.
Even though we mistakenly call “Old Testament” the entire timeline before Jesus, the truth is that the Old Testament was a new ‘age’ which started when God set the Jews free from Egypt and gave the Law to Moses. Abraham had in fact lived in the “age” which was before the “age” of the Old Testament.
Therefore we have at least three ‘ages’ that we easily identify in the Bible: the ‘age’ before the Law, then the ‘age’ of the Law, and then Jesus identified a new ‘age’ that began at the time of John the Baptist, which He called “the Kingdom of heaven“.
The Bible then shows us that there will be a new ‘age’ that will follow after the Second Coming of Jesus (or perhaps, new ‘ages’ will come after that but that is not a subject that should concern us).
What we are trying to understand here is what Jesus said about ‘the end of this age’:
Matthew 13:39 “The enemy who sowed them is the devil, the harvest is the end of the age, and the reapers are the angels. 40 “Therefore as the tares are gathered and burned in the fire, so it will be at the end of this age.
From God’s perspective, there is a “generation” on Earth during the ‘age’ that started with John the Baptist and Jesus, called the Kingdom of Heaven, which will end at the Second Coming of the Lord. It is the generation of this age; “this generation“…
The spiritual concept of “generation” is inherently tied to the spiritual dimension of the “ages” (aeons) which define God’s work in the Earth. Therefore:
