The glory of God is intelligence, or, in other words, light and truth. (D&C 93:36)
For behold, this is my work and my glory—to bring to pass the immortality and eternal life of man. (Moses 1:39)
It is impossible for a man to be saved in ignorance. (D&C 131:6)
“God himself, finding he was in the midst of spirits and glory, because he was more intelligent, saw proper to institute laws whereby the rest could have a privilege to advance like himself. The relationship we have with God places us in a situation to advance in knowledge. He has power to institute laws to instruct the weaker intelligences, that they may be exalted with Himself, so that they might have one glory upon another, and all that knowledge, power, glory, and intelligence, which is requisite in order to save them in the world of spirits.” – Joseph Smith
