Alma 30:53

But behold, the Devil hath deceived me; for he appeared unto me in the form of an angel, and said unto me, Go and reclaim this people, for they have all gone astray after an unknown God. And he saith unto me, There is no God; yea, and he taught me that which I should say. And I have taught his words; and I taught them, because they were pleasing unto the carnal mind; and I taught them, even until I had much success, insomuch that I verily believed that they were true; and for this cause, I withstood the truth, even until I have brought this great curse upon me.

But the Devil tricked me. He appeared to me looking like an angel. He said to me: Go and bring these people back, because they have all gone after an unknown God. He told me: There is no God. He taught me what to say. I taught his words. I taught them because they made sense to the sinful mind. I taught them until I had a lot of success. I believed they were true. Because of this, I fought against the truth until I brought this great curse on myself.

“But the devil deceived me. He appeared to me as an angel and told me: ‘Go and win back these people—they’ve all gone astray after an unknown God.’ He told me there is no God and taught me what to say. I taught his words because they appealed to people’s natural desires. I taught them so successfully that I started believing they were true myself. That’s why I fought against the truth, until I brought this terrible curse on myself.”
