19. 1. The one God is called Jehovah from "being," that is, from the fact that he alone is [and was] and will be, and that he is the First and the Last, the Beginning and the End, the Alpha and the Omega. "Jehovah" means "I am" and "to be," as is generally known. We know from the Book of Creation, or Genesis, that God was called "Jehovah" from most ancient times. In the first chapter he is called "God," but in the second and subsequent chapters he is called "Jehovah God. " Later on the descendants of Abraham through Jacob forgot the name of God owing to their long sojourn in Egypt. Then in the event recorded in the following passage it was recalled to memory:

Moses said to God, "What is your name?" God said, "I Am I Who Am. So you will say to the Children of Israel, 'I Am sent me to you. ' And you will say, Jehovah, the God of your fathers, sent me to you. This is my name to eternity, and this is how I will be remembered from generation to regeneration. " (Exodus 3:13-15)

Since God alone is "I Am" and being, or "Jehovah," therefore nothing exists in the created universe that does not derive its underlying reality from him. (How this happens will be discussed below [21, 75-76, 78].) The same thing is meant by these words: "I am the First and the Last, the Beginning and the End, the Alpha and the Omega" (Isaiah 44:6 and Revelation 1:8, 11; 22:13). This means that on every level of existence he is the one and only entity, the source of all things.

[2] God is called the Alpha and the Omega, the Beginning and the End, because alpha is the first letter in the Greek alphabet and omega is the last; so together they mean all things as a whole.

In the spiritual world, every alphabetical letter has a meaning. A vowel, because it carries tone, means a feeling or some kind of love. Spiritual and angelic speech, and also writing, depends on these meanings - but this is a mystery that has not been known until now. There is in fact a universal language shared by all angels and spirits. It has nothing in common with any human language in our world. After death everyone inherits that language, because it is latent in everyone from creation. In the spiritual world, then, everyone can understand everyone else. I have often been allowed to hear that language. I have compared it with languages in the physical world and have ascertained that it has not even the least thing in common with any earthly language. It differs by its very origin, which is that every letter of every word has a meaning. This is why God is here called the Alpha and the Omega, meaning that on every level of existence he is the one and only entity, the source of all things. (For more on how this language and its written form flow from angels' spiritual thought, see the work Marriage Love 326-329; see also what follows in this work [280].)

23. There is one human God who is the source of everything. All the elements of human reason unite in, and in a sense center on, the fact that a single God is the Creator of the universe. As a result, rational people, on the basis of their shared understanding, neither do nor can think in any other way. Tell people of sound reason that there are two creators of the universe and you will feel within yourself how they recoil from this notion, perhaps simply from the tone of their voice in your ear. This enables us to see that all the elements of human reason unite and center on the oneness of God.

There are two reasons for this. The first is that in its own right, our very ability to think rationally is not our own property. It is a property of God within us. Human rationality in general depends on this fact, and this general property causes our reason more or less spontaneously to see the oneness of God. The second is that through our rational ability either we are in heaven's light or we draw from it some general quality of its thought, and the all-pervading element of heaven's light is that God is one.

This is not the case if we have used our rational ability to skew our lower understanding. In this case we still possess the ability, but by the distortion of our lower abilities we have steered it off course, and our rationality is not sound.
