2 Nephi 31:2 True Doctrine of Christ
True doctrine of Christ is knowledge and information about Christ and also the knowledge and information He teaches, His gospel. True prophets teach true doctrine of Christ; whereas, false prophets and teachers teach false doctrine about Christ and His ways.
Satan instills into the hearts of people falsehoods about Christ to stir them up to anger against that which is true. Salvation cannot be obtained by believing in false doctrine. Jesus said, “And ye shall know the truth, and the truth shall make you free” (John 8:32). Knowing the true doctrine of Christ prevents us from being “tossed to and fro, and carried about with every wind of doctrine, by the sleight of men and cunning craftiness whereby they lie in wait to deceive” (Ephesians 4:14).
