One year as we were preparing instructions for the newly called General Authorities, different members of the Twelve were assigned to prepare a statement on each of the important essential doctrines. One statement was given on the great plan of happiness. Years have passed and I cannot remember who had this assignment, but I have kept his statement in my binder. It explains what we're all seeking. It reads:

“Our Heavenly Father has made available to all His children the same plan, system, and grand design by which He himself became God. It is called the great plan of happiness, the plan of salvation, the gospel of Jesus Christ. It consists of infinite, eternal, absolute, unchanging principles. The plan is complete in every particular, capable of reaching without compulsion to every phase of man's existence from premortal life through mortality and to the resurrection of the body and into eternity. There is no condition of intelligence existing to which the plan cannot be applied if individuals willingly obey. There is no extraneous proviso, nothing to be added or taken away. Although individuals can be blessed through the gospel, the fullness is realized only in the family. The plan is the Father's. Jesus made it His by total obedience to the Father's will. The Creation, the Fall, and the Atonement are essential to the implementation and fulfillment of the plan.”
