I really don't need need the charts and attachments as I'm only responding to what you write.
Yes but Christ ascended into heaven bodily, an important detail you seem to miss.
Adam and Eve's immortality was conditional. Sure, there was nothing in the forbidden fruit itself, it was a test and God barred them from the tree of life. The implication is that had Adam succeeded in protecting Eve from the serpent, maybe they would have had an immutable immortality.
The presence of the Tree of Life in the Garden of Eden implies death was part of the original plan before the fall. We know that eating and reproduction require growth and death processes.
OLD TESTAMENT RESURRECTION: NOT RAISING CORPSES, RATHER, RECONCILIATION TO GOD
A. The Valley of the Dry Bones in Ezekiel 37 conveys relational, figurative resurrection from death when God brought his people back from Babylonian captivity. “And you shall know that I am the Lord, when I shall have opened your sepulchres, and shall have brought you out of your graves, O my people: And shall have PUT MY SPIRIT IN YOU AND YOU SHALL LIVE.” Ezk. 37:13-14
JESUS TAUGHT SPIRITUAL RESURRECTION
A. Jesus, in keeping with Old Testament thought, used the word, “death” for being out of relationship and “life” for reconciliation/restoration/resurrection in the story of the Prodigal Son. In the story of the prodigal son: “My son WAS DEAD and IS ALIVE AGAIN, he was lost and is found. “ Lk 15:24
B. Jesus tells us that union with Him is Life/Resurrection.
• Jesus said to her, "I am the resurrection and the life. He who believes in me will still live, even if he [physically] dies. Whoever lives and believes in me will never die..” John 11:25
• "He who hears my word, and believes him who sent me… has passed out of [spiritual] death into [resurrection] life. John 5:24-5
• “This is eternal life, that they know you, the only true God, and him whom you sent, Jesus Christ.” Jn 17:3
• “It is the spirit who gives life. The flesh profits nothing. The words that I speak to you are spirit, and are life.” John 6:63
C. Jesus’s physical death was a sign. A sign does not point to itself, but to that of greater importance.
“But he answered them, "An evil and adulterous generation seeks after a sign, but no sign will be given it but the sign of Jonah the prophet. For as Jonah was three days and three nights in the belly of the whale, so will the Son of Man be three days and three nights in the heart of the earth.” Mt. 12:39
PAUL TAUGHT SPIRITUAL RESURRECTION The life that now belongs to believers is spiritual life i.e. resurrection/union with Christ.
A. ”You were made alive when you were dead in trespasses and sins… Even when we were dead through our trespasses, [He] made us alive together with Christ.” Eph. 2:1-5
B. “You were dead through your trespasses and the uncircumcision of your flesh. He made you alive together with him, having forgiven us all our trespasses.” Col. 2:13
C. “If by the trespass of the one the many died, much more did the grace of God, and the gift by the grace of the one man, Jesus Christ, abound to the many.” Romans 5:16-17
SALVATION FROM ESTRANGEMENT FROM GOD FREES US FROM THE FEAR OF DEATH.
“Since then the children have shared in flesh and blood, he also himself in the same way partook of the same, that through death he might bring to nothing him who had the power of [spiritual] death, that is, the devil, and might deliver all of them who through fear of death were all their lifetime subject to bondage.” Heb. 2:14-15
