Everything else you've offered is interpolation and interpretation based on post-sin Scripture.
My position: Scripture simply does not say whether Adam was created with or without everlasting life or immortality, with or without a transformation pending. For that matter, Scripture doesn't even explicitly state that Adam and Eve were perfect.
Craig,
Yes some of what I have said is speculation. But scripture is clear on the fact that Adam or any man thereafter would not have lived on endlessly without access to the tree of life. So perfect or not this is not speculation but a refutation of Watchtower theology. That this something was the gift of immortality is not a guess either based upon the immortality our Lord gained for us many years later. Gods plan for man did not change. While not fully explained in Genesis it became a reality in Christ and that is why I was able to put all this together. Christ replaced Adam as the Father of mankind and that is why such comparisons can now be made. The only real difference in this plan for us was sin and time.
Romans 5:14 Nevertheless death reigned from Adam to Moses, even over them that had not sinned after the similitude of Adams transgression, who is the figure of him that was to come.
1 Corinthians 15:22 For as in Adam all die, even so in Christ shall all be made alive.
We can also gather from Genesis the fact that a period of training is required by God before such gifts will be bestowed upon us. This includes justification (something also essential for everlasting life), not just immortality. For Jews such assurance was the Law which assured a better resurrection for them. Faithful followers in Christ under the New Covenant have the hope that they will attain the first resurrection, (first in justification not time along with such immortality) but for others such justification would not take place until after the 1000 years are ended. Gods plan for man and this need to test them did not change just because Adam failed his trial period. Matching such reality with the past was not much of a stretch. But if we do not understand this past or grasp that this same plan will be fulfilled with us and others then how are we to understand what is yet in store for us in the future? It is like getting an overall view of the context in which all scripture should be understood and why we must endure this life in this way.
By grasping this we can know with certainty that no one will simply live on into the promised kingdom without being resurrected or changed. No one can bypass the Christ (as the Watchtower really teaches) and attain everlasting life based upon Adam and the provisions made for him, as his tree of life gone and in Adam all die. There are some things that I do not know for sure. But the fact that Adam was not immortal and would not have lived on and on based upon the life forces within him without further intervention is not one of them.
