"Knowledge saves a man; and in the world of spirits no man can be exalted but by knowledge. So long as a man will not give heed to the commandments, he must abide without salvation. If a man has knowledge, he can be saved; although, if he has been guilty of great sins, he will be punished for them. But when he consents to obey the gospel, whether here or in the world of spirits, he is saved." (Joseph Smith, HC 14:15 p. 314)
