The tree of life was a tangible, literal tree... like the tree of knowledge of good and evil.
The tree of life is NOT a figurative representation of Jesus.
Jesus IS the way truth AND THE Life... but that doesn’t make Him the “Tree of Life”.
God drove out Adam and Eve from the Garden SO THAT THEY WOULD NOT EAT of the tree of life and be lost forever.
Point being, even if you COULD eat of the tree of life today, it would condemn you forever regardless of what you believe... simply because that tree would give eternal life to a corrupted body which must die before it can be resurrected by God back into perfection.
This is a horrible doctrine which borrows from the Lords Supper warning; not to take these sacrements unworthily lest you become sick or die.
The very first negative commandment was “Do not eat of the tree...”. It was a Kosher Law, about what to eat. One could then deduce that it matters to G-d what you eat. It is interesting to note that in Acts 15 the proselites were required to immediately change their eating habits in order to be accepted into the “kahal” of the growing Nazarine movement. Life comes as a result of obedience and, I have it on good authority that death is the result of disobedience. “Choose Life”, eat properly, be well, and may the G-d of Israel bless you in all that you do.
