Disobedience to the Lord’s commandments allows Satan to deceive us, and we forget the light and truth we have previously learned. President Henry B. Eyring of the First Presidency described this dangerous condition: “One of the effects of disobeying God seems to be the creation of just enough spiritual anesthetic to block any sensation as the ties to God are being cut. Not only [does] the testimony of the truth slowly erode, but even the memories of what it was like to be in the light [begin] to seem … like a delusion” (“A Life Founded in Light and Truth,” Brigham Young University 2000–2001 Speeches [2001], 81).
