How do I know what I am feeling is the Spirit and not just my own emotions?

We sometimes hear stories in which the Spirit speaks audibly or through visions or strong impressions. But more often, revelation comes quietly (see D&C 6:23; 8:2–3; 1 Kings 19:11–12).

President Brigham Young (1801–1877) said: “The Spirit of God filling the creature with revelation and the light of eternity, cannot be mistaken” (Teachings of Presidents of the Church: Brigham Young [1997], 319).

Search your own experience. Remember how you’ve felt when you’ve prayed, studied the scriptures, or had other experiences with the Spirit. Continue to do those things and seek out those experiences. Learn to recognize those feelings that enlighten and speak peace to your mind and that encourage you to believe in Christ, love others, and do good. As you do so, you will learn what President Young was talking about.
