If we are not obedient to the laws, principles, and ordinances of the gospel, the Holy Ghost will withdraw. He cannot be with us if we are angry in our hearts, contentious with our companions, or critical of the Lord's anointed. He departs whenever we are rebellious, are immoral, dress or act immodestly, are unclean or profane in mind or body, are slothful in priesthood callings and duties, or commit other sins, for "the Spirit of the Lord doth not dwell in unholy temples." Therefore we must continually repent, partake of the sacrament, be worthy of a temple recommend, and serve the Lord with all our "heart, might, mind and strength."
