Just a random thought that came to me while studying the Qabalah. In the Apocalypse of John, there are three visionary scenes where Christ reveals, “I am the Alpha and the Omega” (Rev 1:8, 21:6, and 22:13). Which as many would know, is equivalent to saying, “I am the A and the Z.”
But hang on, aren't we forgetting something here? In the Hebrew language (and remember, Christianity came out of Judaism) this would have been equivalent to saying, "I am the Alef and the Tav." Which also happen to be the first and last paths on the Qabalistic Tree of Life. Which you can see well enough for yourself if you click on this Qabalistic diagram to the left.
This is to be expected, as Qabalah began as meditations on the letters and numbers of the Hebrew language. This language being considered sacred, the very word of God, by Hebrew mystics.
So it may be said that the Apocalypse of John reveals that the Tree of Life is Jesus, the way to God from beginning to end.
