There is a tree in
Heaven
called the
tree of life.
Revelation 22:2
...the tree of life,
bore twelve fruits, each tree yielding its fruit
every month.
The leaves of the tree are for the service of the nations.
The following teaching is from The Revelation Record
by the late and highly esteemed Dr. Henry Morris.
Furthermore, the tree of life is not rare, but prolific,
growing in profusion all over the world. In the new Jerusalem,
it grows along the esplanade in the center of all the golden streets
and lines both banks of the cascading river. Presumably outside the
city it grows along the shores of all the multitudes of distributaries
of the mighty river as they spread out through all the regenerated world.
Finally, the necessity to continually partake of the life-giving fruit from the tree
and water from the river will be a continual testimony
to the people of the new earth that their Creator and Savior is Himself
the source of life and breath and all things. And this knowledge and
requirement will never become a burden
but will always remain a joy and a
delight.
