The gift of the Holy Ghost, if you consent, will guide and protect you and even correct your actions. It is a spiritual voice that comes into the mind as a thought or a feeling put into your heart. . . . It is not expected that you go through life without making mistakes, but you will not make a major mistake without first being warned by the promptings of the Spirit. This promise applies to all members of the Church.
