The Lord, in the simplest terms, is love itself expressed as wisdom itself. In philosophic terms, love is the Lord's substance and wisdom is His form. Of course, we feel the Lord's love and hear His wisdom in many different ways, depending on our state in life and how receptive we are. That's why the Lord has so many different names in the Bible, and is referred to in so many different ways.

29. "I am the Alpha and the Omega, the Beginning and the End." (1:8) This symbolically means, who is the one and only reality from firsts to lasts, from whom springs all else, thus who is the one and only love, the one and only wisdom, and the one and only life in itself, and so the one and only Creator, Savior and Enlightener from Himself, and therefore the all in all of the church and heaven.

These and still more are the ideas contained in these words, which describe the Lord. It is clearly apparent that they are said of the Lord, and indeed of His humanity, for we are told next that John heard a voice saying, "I am the Alpha and the Omega, the First and the Last," that he turned to see the voice that spoke with him, and that he saw the Son of Man in the midst of the seven lampstands (Revelation 1:10-13) - who shortly also said, "I am the First and the Last, and am He who lives, and was put to death" (Revelation 1:17-18, cf. 2:8).

As for all the particulars listed above, however, it is impossible to confirm these briefly, since to confirm them to people's comprehension would take many pages. Still, we have confirmed them in part in Angelic Wisdom Regarding Divine Love and Wisdom, recently published in Amsterdam, q.v.

The Lord calls Himself the Alpha and the Omega, the Beginning and the End, because Alpha and Omega have reference to His Divine love, while Beginning and End have reference to His Divine wisdom. For present in every particular of the Word is a marriage of love and wisdom or of goodness and truth, on which subject see The Doctrine of the New Jerusalem Regarding the Sacred Scripture, nos. 80-90.

[2] The Lord is called the Alpha and the Omega because alpha and omega are the first and last letters of the Greek alphabet, and they consequently symbolize all things in their entirety. That is because in the spiritual world every alphabetic letter has some symbolic meaning, and a vowel, since it serves to provide tone, symbolizes something having to do with affection or love. From this origin springs spiritual and angelic speech, and also writing. But this is an arcanum previously unknown. For there is a universal language, which all angels and spirits possess, and it has nothing in common with any language of people in the world. Everyone comes into use of this language after death, as it is implanted in everyone from creation. Everyone can therefore understand everyone else throughout the whole spiritual world. I have been granted often to hear that language, and also to speak it, and I have compared it with languages in the world and found that it does not accord, even in the least particular, with any natural language on earth. It differs from them from its first characteristic, which is that every letter in each word has some symbolic meaning, both in speaking and in writing.

That, then, is why the Lord is called the Alpha and the Omega, which symbolically means that He is the all in all things of heaven and the church. And because they are both vowels, they have reference to love, as said above.

Regarding this language and the writing of it flowing from the spiritual thought of angels, see also some observations in Angelic Wisdom Regarding Divine Love and Divine Wisdom, no. 295.
