Intelligence is material in nature.
When we are eventually born into mortality, our physical bodies are in the likeness of our spirit bodies. They taught us as much as we were able to comprehend as spirits. However, in our premortal state we were limited in our ability to achieve a fulness of happiness, such as enjoyed by our Heavenly Parents. In order for us to overcome evil and enjoy eternal felicity, it was necessary for us to acquire a physical body which could later be resurrected into an immortal one. As the presiding priesthood authority in heaven, our Heavenly Father called a great meeting of his spirit children, which has alternatively been called the Council in Heaven or the Grand Council.
