“For everyone, at every stage of purification, there are constants. One is this: reception of the Holy Ghost is the cleansing agent as the Atonement purifies you … .
“That is a fact you can act on with confidence. You can invite the Holy Ghost’s companionship in your life. And you can know when he is there, and when he withdraws. And when he is your companion, you can have the confidence that the Atonement is working in your life” (Eyring, To Draw Closer to God, 49–50).
