The light of truth. The light of Christ. He is the light of the sun and the power thereof. He is the light of the moon and the power thereof. He is the light of the stars and the power thereof. The earth also, and the power thereof. The light in all things, even the power of God which sitteth upon the throne.

-thus D&C 88:5-13.

Now, one might say truthfully that glory = power plus light. Righteous power = power plus light. But the scriptures say that you cannot even really separate the two concepts. Power without light is ultimately not actually power. Light without power is ultimately not actually light.
