Letter Alpha and Letter Omega

The Judeo-Christian tradition gives us the concept of Alpha and Omega. “I am Alpha and Omega, declares the Lord, what is, what was, and what is to come, the Whole Powerful,” says the Lord in the first chapter and eighth verse of the book of Revelation.

Because the letter Alpha is the first and the letter Omega is the last in the Greek alphabet, it is clear that God is both the beginning and the end of everything. Therefore, everything begins with divinity and concludes with deity, which is eternal.

Because the Bible was translated from Greek, we refer to Alpha and Omega in this line; nevertheless, if it were written in Portuguese, the equivalent would be “I am A and Z.”

God has always been and will always be, according to the notion. Therefore, God is the one who created everything and determines when everything begins and finishes.

Another biblical reference to such an idea can be found in Genesis 3:19, where the phrase “For you are dust, and to dust, you will return” is used. It should be noticed that the reference is made to the beginning and end of something. The man God created out of the dust of the ground will decompose and return to the dust.

In addition to the Judeo-Christian tradition, spiritualist religions hold that human consciousness is a divine spark that has separated from the Supreme Being to experience human life, evolve, and reintegrate with the divine, this time in universal cosmic consciousness.
