D&C 93

 In this revelation, we learn additional truths that may not be as clear in the Bible.  The Lord teaches - 

"Ye were also in the beginning with the Father; that which is Spirit, even the Spirit of truth (or Jesus Christ)"  (Doctrine and Covenants 93:23)

"The Spirit of truth is of God. I am the Spirit of truth, and John bore record of me, saying: He received a fulness of truth, yea, even of all truth..."  (Doctrine and Covenants 93:26)

"Man was also in the beginning with God. Intelligence, or the light of truth, was not created or made, neither indeed can be."  (Doctrine and Covenants 93:29)

"For man is spirit. The elements are eternal, and spirit and element, inseparably connected, receive a fulness of joy;"  (Doctrine and Covenants 93:33)

"The glory of God is intelligence, or, in other words, light and truth.

37 Light and truth forsake that evil one."  (Doctrine and Covenants 93:36–37)

"But I have commanded you to bring up your children in light and truth."  (Doctrine and Covenants 93:40)
