A simple examination of the word, "eternal", and the words "forever and ever" will reveal their original Greek roots and their meanings. "Eternal" is an unfortunate mistranslation from the Greek word aionios which means "of the ages" or "age abiding". It is rightly translated this way in a few translations, such as Rotherhams's , emphasized Bible, the Concordant New Testament, and Young's literal translation. The origin of these words can also be confirmed, using a Strong's or Youngs Literal translation, Vines dictionary, or by any number of other studies that deal with the Greek language. Darrell Scott.
Weymouth New Testament
For so greatly did God love the world that He gave His only Son, that every one who trusts in Him may not perish but may have the Life of Ages. John 3:16
Young's Literal Translation
for God did so love the world, that His Son -- the only begotten -- He gave, that every one who is believing in him may not perish, but may have life age-during. John 3:16
Weymouth New Testament
He who holds his life dear, is destroying it; and he who makes his life of no account in this world shall keep it to the Life of the Ages. John, 12:25
Young's Literal Translation
he who is loving his life shall lose it, and he who is hating his life in this world -- to life age-during shall keep it; John 12:25
When the same Greek word is translated, eternal in one place, and never in another, then world in another, we lose the content of God's message to us. This total inconsistency and proper translation, has caused God's purpose for the ages to be obscured. Many Christians are shocked when they first find out about the inconsistencies of translations.

The definition of eternal life has no beginning and no end .
Jesus conquered death, and gives life out of death, Never, to die again. That is the life we receive from Him.
So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory. 1 corinthians 15:54
