One of the things that the Celtic and Jewish expressions of faith have in common is the Tree of Life.
In Jewish tradition, Torah is the Tree of Life, Etz Chayim, the Way by which we can heal the world and regain the beauty and blessings of the Garden of Eden.
In Messianic Jewish thought, Jesus is the Living Torah, or the living embodiment of Torah and therefore Jesus Himself is the Tree of Life.
It is a tree of life
Join and take hold of it
Blessed are those in its ways
It’s full of pleasantness
All of its ways hold peace
Bring us L-rd to you renewed
