In the context of Latter-day Saint teachings, "intelligence," “soul,” and “spirit,” are sometimes used interchangeably and other times not. For Latter-day Saints, there exists an eternal aspect of our identity. According to Doctrine & Covenants 93:29, "Man was also in the beginning with God. Intelligence, or the light of truth, was not created or made, neither indeed can be." This scripture suggests that intelligence is an essential and eternal part of our spirit. It is not something that was created or at any point not part of our existence. This means that, in a sense, we have always existed in some form.

In the Book of Abraham, Abraham sees a vision where God shows him the "intelligences" that were organized before the world was. Abraham 3:22-23 highlights this concept: "Now the Lord had shown unto me, Abraham, the intelligences that were organized before the world was; and among all these there were many of the noble and great ones."

Here, intelligence is depicted as a pre-existent form of being. This indicates a state of existence prior to our mortal life, where we were individuals with agency and identity.

The eternal nature of intelligence is key to understanding our purpose and destiny according to Heavenly Father's plan. The idea is that because we have always existed, our mortal experience is just one part of a much larger eternal journey. The decisions we make here, aided by our intelligence, are crucial for our progression.

The Doctrine & Covenants also relates intelligence to light and truth. Doctrine & Covenants 93:36 states, "The glory of God is intelligence, or, in other words, light and truth." This indicates that intelligence is closely tied to divine attributes.

In Latter-day Saint theology, intelligence is an eternal part of us that was not created, has always existed, and plays a crucial role in our spiritual journey. It’s through intelligence that we grow, learn, and progress towards becoming more like our Heavenly Father.
