This statement by God to Moses had to be the most significant statement made about Himself, not what the Mormons said He stated. The fact that God would be considered ‘intelligence’ comes from the book of First John when he tried to explain to the Gnostics that salvation is not through intelligence, but through Christ Jesus and Him crucified. By the way, intelligence does not mean light and truth.
I AM THAT I AM is translated to YHWH in the Hebrew. It is used over 6,000 times in the Old Testament alone. It is by far the most holy name of God and to be used only with the utmost respect and reverence.
The Israelites understood it to mean that this rendition of His name was too holy to utter aloud, thus their usage of the name Adonai (Jehohvah).
“God concluded His explanation to Moses with the most significant and most marvelous statement regarding the work and glory of God to be found in religious literature. He declared: For behold, this is my work and my glory—to bring to pass the immortality and eternal life of man. Another declaration which is almost equally as important as the one just cited was given to the Prophet Joseph Smith by revelation. It is: “The glory of God is intelligence, or, in other words, light and truth.”” Milton R. Hunter, The Gospel through the Ages, 6.
