“What is the gift of discernment?” Liahona, June 2018
The scriptures talk about the “discerning of spirits” as a gift of the Spirit (1 Corinthians 12:10; D&C 46:23). It means “to understand or know something through the power of the Spirit. … It includes perceiving the true character of people and the source and meaning of spiritual manifestations” (Guide to the Scriptures, “Discernment, Gift of,” scriptures.lds.org).
Elder David A. Bednar of the Quorum of the Twelve Apostles has taught that the gift of discernment can help us (1) “detect hidden error and evil in others,” (2) “detect hidden errors and evil in ourselves,” (3) “find and bring forth the good that may be concealed in others,” and (4) “find and bring forth the good that may be concealed in us” (“Quick to Observe,” Liahona, Dec. 2006, 19).
