I do wonder at why someone would behave in this manner and then turn round and say they do not.
dunno why you cannot be said to be living in "eternity" right now, wadr. Eternities end just like aeons do i guess, however terrible that is for one's belief system, particularly the Cult of Sol Invictus, oh well
I dug a little deeper.
If eternal means without beginning or end exclusively, we cannot be made eternal, because everything eternal in this sense is God.
So a lot of the uses of eternal are in regard to their continuation without end.
When an attribute of God they have no beginning or end.
So an adjective can have more than one implication depending on the subject, noun, it is referring to.
Also eternal can be a pointer to a type of the subject applied from one context to another.
So Paul says we inherit life through righteousness, or death through sin.
8 The one who sows to please his sinful nature, from that nature will reap destruction; the one who sows to please the Spirit, from the Spirit will reap eternal life.
Gal 6:8
If this is an equation between opposites, eternal life is the opposite of destruction.
7 Do not be deceived: God cannot be mocked. A man reaps what he sows.
Gal 6:7
Now this could be written to unbelievers except the letter is for believers, and about those believers caught in sin.
1 Brothers, if someone is caught in a sin, you who are spiritual should restore him gently. But watch yourself, or you also may be tempted.
Gal 6:1
Now if we sow to the Spirit and reap eternal life, and this life is now God, so we are now gods, you can see how the small gods heresy can spring from a restricted view of one word, eternal.
