Everything that exists flows from Him, self-existent and uncreated; He would not have brought forth anything if He had not first envisioned it, nor would He have envisioned it if it did not exist within Him uncreated—this eternal and immutable essence, indescribable and beyond human expression, can only be conveyed through temporal and spatial references, despite transcending them entirely.
He is undoubtedly a substance, or more fittingly, an essence, corresponding to the Greek term ousia. Just as “wisdom” derives from “wise,” and “knowledge” is rooted in “to know,” so “Essence” emerges from “being.” Indeed, who is greater than He who stated to His servant, “I am the Being,” instructing, “Thus say unto the children of Israel, The Being hath sent me unto you”? Other entities, referred to as essences or substances, are subject to change, undergoing various degrees of transformation. However, such alterations are impossible for God. Therefore, the unchanging essence that is God is unique, perfectly aligning with the term essence itself.
Marvelously, our Lord proclaimed to His servant, “I am the Being,” and commanded, “Say unto the children of Israel, The Being hath sent me unto you.” He exists in His unchanging nature; any form of change would imply the cessation of existence, affirming that He who does not change indeed exists. All other beings that were created emerged from Him, beginning their existence through Him.
The One who exists supremely and originally, entirely unchangeable, affirmed, “I am the Being,” and instructed, “Say to them, The Being sent me to you,” signifying that all other realities find their existence through Him and are deemed good to the extent that they recognize their being.
Scripture powerfully reflects Plato's assertion that a philosopher is one who loves God. A compelling reason for considering that Plato had knowledge of such truths is found in the dialogue where the angel conveyed God’s message to Moses. When Moses asked for the name of the one commissioning him to lead the Jewish people out of Egypt, the response was, “I am He who exists.” He was directed to convey to the children of Israel that “The Being hath sent me unto you.” This implies that, in comparison to Him who genuinely exists and remains unchangeable, all created things, being changeable, do not truly exist. This was a conviction that Plato deeply embraced and pursued. Such a thought seems rare in the works of those before him, except for this particular instance.
Though this unchanging and ineffable Divine essence does not encompass the notions of “was” or “will be,” it solely embodies “is,” representing the very essence of being, for it cannot change. Thus, it is appropriate for Him alone to declare, “I am the Being,” instructing, “Say unto the children of Israel, The Being hath sent me unto you.” Yet, due to the transient nature of our mortality, we confidently speak of God as “He was, and is, and will be.” His “was” indicates there was never a time He did not exist; “will be” signifies that there will never be a moment when He ceases to exist; and “is,” because He perpetually exists. It may have been challenging for Moses to grasp this truth, and it may prove even more difficult for us to understand what it means when He states, “I am He who is,” and, “He who sent me to you.” Even if Moses apprehended this revelation, how could those to whom he was sent have comprehended it? Therefore, the Lord presented Himself in a manner comprehensible for humanity, affirming, “I am the God of Abraham, the God of Isaac, and the God of Jacob” (Ex. 3:6). While this is understandable, who can truly grasp the significance of “I am the Being”?
When He refers to another name, declaring, “I am called the Being,” and additionally identifying as “I am the God of Abraham, and the God of Isaac, and the God of Jacob” (Exodus 3:6), we perceive a profound truth. Despite God's unchangeable nature, which created all things out of love, the Son of God chose to don transient flesh while remaining the Word of God, coming to redeem humanity. Thus, He who was One, took upon Himself mortal flesh, enabling the proclamation, “I am the God of Abraham, and the God of Isaac, and the God of Jacob.” When Moses inquired about God's name, he received the response, “I am the Being,” instructed to convey to the children of Israel that “The Being hath sent me unto you.” What does this mean? O God, our Lord, what is Your name? He replied, “I am called the Being.” What does it signify, “I am called the Being”? I dwell in eternity, for I am immutable. That which changes does not truly exist, as it is impermanent. What exists endures. Changeable entities had a beginning and an end but do not truly exist, as they are subject to transformation. Thus, the immutability of God is aptly encapsulated in this declaration: “I am the Being.”
