Note: I acknowledge that there is no suppose private interpretation of the bible scripture (II Peter 1:20) hence, I subject this writing to other spirit. Should you find my writing to be totally wrong, I would then appreciate if you could correct me and or rebuke me (II Timothy 3:16). Let's reason together (Isaiah 1:18) so as to bring the matter into the light, I can be reach at firstname.lastname@example.org.
Two trees were emphasise in the creation story the "Tree of Life" and the "tree of good and evil"
"The Lord God made all kinds of trees grow out of the ground—trees that were pleasing to the eye and good for food. In the middle of the garden were the tree of life and the tree of the knowledge of good and evil. (Genesis 2:9 NIV)"
God commanded that they can eat "ANY" tree in the garden except the tree of the knowledge of good and evil.
"And the Lord God commanded the man, “You are free to eat from any tree in the garden; but you must not eat from the tree of the knowledge of good and evil, for when you eat from it you will certainly die.” (Genesis 2:16-17 NIV)"
Notice that the aforementioned tree was the only one not allowed to be eaten, therefore implying that they were allowed to eat the tree of life as long as they don't eat the other one. The tree of life was for them to supposedly live forever.
"And the Lord God said, “The man has now become like one of us, knowing good and evil. He must not be allowed to reach out his hand and take also from the tree of life and eat, and live forever.” (Genesis 3:22 NIV)"
The punishment of eating the tree of knowledge is that they will certainly die. By forbidding the man not to eat the tree of life after they defy the only commandment, the man will now certainly going to die, God did not specifically mentioned when but it will certainly happen. And it did.
"Altogether, Adam lived a total of 930 years, and then he died. (Genesis 5:5 NIV)"
To date, nobody escape death, it always has been the wages of sin, “For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.” Romans 6:23 NKJV" which proves that we did inherit the first sin our ancestor had committed. Unless God intervened, no one has been exempted in the past neither today nor tomorrow as His word has long been established from the beginning that, once said it will not come back empty:
"so is my word that goes out from my mouth: It will not return to me empty, but will accomplish what I desire and achieve the purpose for which I sent it. (Isaiah 55:11 NIV)"
