13. From Him who is and who was and who is to come. This symbolically means, from the Lord who is eternal and infinite, and who is Jehovah.

That it is the Lord is clearly apparent from verses that follow in this chapter, where it is said that John heard a voice from the Son of Man saying, "I am the Alpha and the Omega, the First and the Last," and afterward, "I am the First and the Last" as well as in the next chapter, 2:8, and later in 21:6; 22:12-13). Also in Isaiah:

Thus says the Lord, the King of Israel, and his Redeemer, Jehovah of Hosts: "I am the First and I am the Last, and besides Me there is no God." (Isaiah 44:6; also 48:12)

Moreover, He who is the First and the Last is He who is, who was, and who is to come.

[2] This also is the meaning of "Jehovah." For the name "Jehovah" means "He is" and "He who is," or He who is being itself. ¹ It also means "He was" and "He is to come," since the past and the future in Him are present. Consequently He is eternal independently of time, and infinite independently of place.

The church also confesses this in conformity with the doctrine of the trinity called the Athanasian Creed, where these words are found:

The Father is eternal and infinite, the Son is eternal and infinite, and the Holy Spirit is eternal and infinite. And yet there are not three eternal and infinite Gods, but one.

That one is the Lord, as we demonstrated in The Doctrine of the New Jerusalem Regarding the Lord.
