The tree of life, a symbol of God's inner presence?

In answer to the video "Allah is NOT Forgiving, Merciful or Loving"

That is only wishful thinking, unsupported by the plain meaning of the text. The primary purpose for which Adam and Eve were created, was to fill the earth and rule over the living creatures Gen1:28-29,2:5. They were created from the ground of the earth (not heaven) Gen2:7-8.

Adam and Eve's "immortality" was tied to eating from the Tree of Life, which they could freely access as the Garden of Eden's caretakers Gen2:15-17. Since their "immortality" was conditioned on their staying in the Garden of Eden, it means that they were actually mortal human beings who were able to benefit from the privilege of eating the fruit of the Tree of Life to stay alive indefinitely.

Their transgression, marked by the eating from another tree, the tree of knowledge, which imbued them with consciousness of both good and evil resulted in their expulsion from the Garden of Eden.

With that expulsion, their ability to eat from the fruit of the Tree of Life stopped. Had they kept eating from the tree of life, now that they are aware of not only good, but also evil, the result could have been that spiritualy degenerate people and criminals might live forever. A type of angel, an angel of destruction, the cherubim was tasked with guarding the garden's entrance to prevent that eventuality.

Thus the result of their expulsion is that they eventually died. Despite certain important variations, many fundamental aspects remain in the HB and parallel with the Quranic account, including the fact that it must have been God's plan from the beginning to ultimately place mankind on the earth, as His vicegerents 2:30. The main areas where the Quran disagrees with the Torah is that in the latter, the knowledge of good and evil were concealed from man in a "tree of knowledge" whereas the Quran clearly states that this spiritual feature is ingrained and hardwired in man 91:7-10.

According to the interpolated HB, when man ate from the tree of the knowledge of good an evil, man "became like one of us", against God's will and desire. According to the Quran, God "breathed into man of his spirit" and in sura Shams, defines it as

"He inspired the soul with the knowledge of evil and good",

meaning he was meant to "become like us". The HB still contains elements of this reality when it states that man was created in the "image of God".

This is one of many examples of Quranic intertextuality, the Quran's purposeful engagement with the biblical narrative, correcting it in a profound manner in accordance with its own distinctive theological message.

We thus see the Quran giving a consistent, comprehensive picture of creation from the beginning. Mankind were made mortals from the start 2:30 so as to allow them to be tested in their spiritual resolve and ultimately held accountable in the afterlife 

67:1-2"Blessed is He in whose hand is dominion, and He is over all things competent - who created death and life to test you [as to] which of you is best in deed - and He is the Exalted in Might, the Forgiving". 

All tools are put at man's disposal to pass this test; both inner and outward. Senses of spiritual perception to derive the higher meaning from the constant processes of this universe, and direct guidance through chosen individuals who communicate the will of the Creator. All these arrangements do not necessitate that man will succeed, or else there would be no test. Rather man was created as a volitional creature, with a neutral spiritual nature 30:30 that is shaped and developed according to one's moral choices throughout life 91:7-10. Death is therefore not an accident, nor is mankind of flawed spiritual disposition. In the Christian model, the purpose of man was redefined in the course of history. Although he was first made to live forever in heaven, man's disobedience sent him to this world and caused him to wander aimlessly as all his thoughts and deeds became stained with sin. At one point God created a device to compensate for that inherent human flaw, which is a divine sacrifice, thereby giving man a new purpose; accepting Jesus' sacrifice.
