In the very centre of Paradise, in the midst of the land of Eden, grew the Tree of Life. Now, what was this tree? Various have been the conjectures with regard to its nature. The traditions of the Rabbins make the Tree of Life a supernatural tree, resembling the world- or cloud-trees of the Scandinavians and Hindus, and bearing a striking resemblance to the _Tooba_ of the Mahomedan Paradise. They describe the Tree of Life as being of enormous bulk, towering far above all others, and so vast in its girth, that no man, even if he lived so long, could travel round it in less than five hundred years. From beneath the colossal base of this stupendous tree gushed all the waters of the earth, by whose instrumentality nature was everywhere refreshed and invigorated. Regarding these Rabbinic traditions as purely mythical, certain commentators have regarded the Tree of Life as typical only of that life and the continuance of it which our first parents derived from God. Others think that it was called the Tree of Life because it was a memorial, pledge, and seal of the eternal life which, had man continued in obedience, would have been his reward in the Paradise above. Others, again, believe that the fruit of it had a certain vital influence to cherish and maintain man in immortal health and vigour till he should have been translated from the earthly to the heavenly Paradise. Dr. Wild considers that the Tree of Life stood on Mount Moriah, the very spot selected, in after years, by Abraham, whereon to offer his son Isaac, the type, and the mount to which Christ was led out to be sacrificed. As Eden occupied the centre of the world, and the Tree of Life was planted in the middle of Eden, that spot marked the very centre of the world, and it was necessary that He who was the life of mankind should die in the centre of the world, and act from the centre. Hence, the Tree of Life, destroyed at the flood, on account of man’s wickedness, was replaced on the same spot, centuries after, by the Cross,--converted by the Redeemer into a second and everlasting Tree of Life.
