Furthermore death had not entered into the world until the fall. It was the fall that brought death upon man. So I would say that Adam did have eternal life before the fall then it was revoked.
We all have eternal life., but not all have the Specific type that is this.....Jesus said. "I am The Way, The Truth, and THE
LIFE".
See that life?
That is the eternal life that Jesus speaks about here....= "All that believe in me, i give unto them ETERNAL LIFE, and they shall never perish".
So, that is Christ's life that is our Spiritual Union with God, (Born again)>..., that John teaches this way.....>"you can KNOW you have eternal life".....by being born again "in Christ".
But then there is this.....
Everyone is a spirit being in a dying body. And this spirit being who is the real you, does not die. it just continues.
Your body will be cremated or buried in a box, but the real you, the spirit < = is gone to a final destination that begins with your body dies, as this releases your spirit.
When you read about the "2nd Death".......being Hell and the Lake of Fire........this is not the death of the Spirit.... this is the permanent separation from God, into that situation.
See, the 1st Death, the first separation, was Adam's fall.. "In adam we all die"........but not spiritually.....as this is the separation from God that Jesus came to restore for us on the Cross.
The 2nd Death, is to die unredeemed, never born again and there is no 2nd Chance given to trust in Christ after you die, so, that is the last separation from God., or the 2nd and final. = Dying never being born again. = The 2nd Death.
Its like this......as long as you are breathing, is your last chance to become "one with God", "In Christ", and die having eternal life.. born again.
Jesus said....>"You must be born again" or you dont Join God's Spirit and you die that 2nd Death, = eternal separation from God.
Once you are dead, you have entered this 2nd Death, or the endless separation from God....that is a death (Separation from God) that continues for eternity.
