Elder LeGrand Richards made this statement: "I would rather have my children and my children's children enjoy the companionship of the Holy Ghost than any other companionship in this world because if they will heed the promptings of that Spirit, he will lead them into all truth and see them safely back into the presence of their Father in heaven" (in Conference Report, Apr. 1966, 112; or Improvement Era, June 1966, 540).

Because the guidance of the Holy Ghost is so important, we should do all we can to be worthy of His companionship.

There are many things we can do to keep the Holy Ghost with us. One way is to partake of the sacrament worthily. Each time we partake of the sacrament, we promise that we will obey the Lord's commandments. If we keep our promise, the Lord has promised us that we can "always have his Spirit" with us. (See D&C 20:77.)
Another way to keep the Holy Ghost with us is to keep our bodies morally clean. The Apostle Paul taught that our bodies are like temples and that we must not defile them (see 1 Corinthians 3:16 - 17). The Holy Ghost cannot dwell in unclean temples; it is important, therefore, that we keep our bodies clean and pure in thought, speech, dress, and action, avoiding even the appearance of evil....

To keep the Holy Ghost with us, we must live in harmony with those around us. Speaking to the Nephites, Christ said that the spirit of contention comes from the devil (see 3 Nephi 11:29). The Holy Ghost cannot dwell where disunity and disharmony exist. For this reason, arguing with our wife or quarreling with a brother or sister will drive the Holy Ghost away from us and from our homes.

If I make good choices, I make it possible for the Holy Ghost to help me choose the right.
