SoP,
It's most relevant that God put two trees in Eden, the tree of Wisdom and the Tree of Life. It's also relevant that God only made express mention prohibition towards the Tree of Wisdom, while no such stern warning is given towards the Tree of Life - and yet, God puts no guards around the Tree of Wisdom, while putting guards and a revolving sword to keep A & E at bay from the Tree of Life. What do you make of it?
In my opinion, the order on which the trees are presented has significance. It appears that you can only access eternal life after you have gained wisdom.
Makes no sense to reason that God has put the Tree of Wisdom in the garden as a test to Adam and Eve. That goes against the principle described in James 1:13 -"God doesn't tempt anyone [with evil]". Rather, God is described as the source of "every good and perfect gift" (James 1:17). That tree was there because at some point God would allow that couple to eat its fruit, and gain wisdom - wisdom that would prepare them step into a higher level of life, the spiritual life. After that, they would be ready to eat from the Tree of Life, marking their passage from the material world into the spiritual realm, where they would enjoy eternal life.
(Turns out that Satan told Eve a half truth - by eating from the Tree of Wisdon, they would become "like God". What he didn't mention was, in doing so in disregard of God's orders, they were severing the spiritual bond of sonship with God and their access to the spiritual realm altogether. Who knows? Maybe Satan was jealous that God had granted inferior creatures the possibility to raise to spiritual beings status, and he decided to take matters into his own hands and screw God's plans).
Without wisdom, they could eat as many times as they might from the Tree of Life - they just wouldn't live forever here on earth. God wasn't concerned with keeping them from access to the Tree of Life until the moment they ate from the Tree of Wisdom. Why would God be worried that they would take the fruit from the Tree of Life and live forever if they had already sinned and therefore were to die anyway? What do you make of that also?
