Perhaps the most confusion of understanding on this subject is the lack of understanding of the Greek word translated either as age, world, ever, forever and with other translated version words. In Koine Greek this is the word aion, which is also written in English as aioon. When seeing the following biblical usages of this word aion, a clear definition is age with a limited duration of time, or a period of longer or shorter duration having a beginning and an end. When seeing other biblical usages, which will be covered on the final page of this study, this word could also be understood and used in context as an unbroken age, perpetuity of time, eternity. However, this usage would require multiple ages and as it relates to God the creator of life. This Greek word is used as a noun. There are 125 usages of this word in the New Testament. From a number of usages of this word it is clearly seen that age has a limitation of time with an end to the age. In the King James Version this is often translated world. However, most if not all of the newer biblical versions use the word age for aion more often. Below are versus with aion from the King James Version, followed by other biblical versions chosen randomly. As I stated previously, with editing biblical versions can improve for truth and clarity.
39 The enemy that sowed them is the devil; the harvest is the end of the world (aion); and the reapers are the angels. 40 As therefore the tares are gathered and burned in the fire; so shall it be in the end of this world (aion).
King James Version (KJV)
39 and the enemy who sowed them is the devil. The harvest is the end of the age (aion), and the reapers are angels. 40 Just as the weeds are gathered and burned with fire, so will it be at the end of the age (aion).
English Standard Version (ESV)
49 So shall it be at the end of the world (aion): the angels shall come forth, and sever the wicked from among the just,
49 So it will be at the end of the age (aion); the angels will come forth and take out the wicked from among the righteous,
New American Standard Bible
3 And as he sat upon the mount of Olives, the disciples came unto him privately, saying, Tell us, when shall these things be? and what shall be the sign of thy coming, and of the end of the world (aion)?
3 And as he sat upon the mount of Olives, the disciples came unto him privately, saying, Tell us, when shall these things be? and what shall be the sign of thy coming and of the end of the age (aion)?
Jubilee Bible 2000
20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world (aion). Amen.
20 teaching them to obey everything I have commanded you. And remember, I am with you always, to the end of the age (aion).
New English Translation
Clearly from the above usages age or aion in the Greek has an ending. From the next usages age or aion also has a beginning. The first two of the below verses also includes the related Greek word aionios, which is used as an adjective. This is not a literal word for eternal as it relates to aion or age. Instead it is related to describing one of God's many attributes as being the God of the ages, while resigning supreme in his time bound plan of life for mankind. We will see this in more detail later in this study.
30 But he shall receive an hundredfold now in this time, houses, and brethren, and sisters, and mothers, and children, and lands, with persecutions; and in the world (aion) to come eternal (aionios) life.
30 who may not receive an hundredfold now in this time, houses, and brothers, and sisters, and mothers, and children, and fields, with persecutions, and in the age (aion) that is coming, life age-during (aionios);
Young's Literal Translation
30 Who shall not receive manifold more in this present time, and in the world (aion) to come life everlasting (aionios).
30 who will not receive manifold more in this time, and in the age (aion) to come eternal (aionios) life."
