Discourses of Joseph Smith, pg. 270; “—Will everybody be damned, but Mormons?…Yes, and a great portion of them, unless they repent, and work righteousness.”
2 Peter 3:2-5; “That ye may be mindful of the words which were spoken before by the holy prophets, and of the commandment of us the apostles of the Lord and Saviour: 3 Knowing this first, that there shall come in the last days scoffers, walking after their own lusts, 4 And saying, Where is the promise of his coming? for since the fathers fell asleep, all things continue as they were from the beginning of the creation. 5 For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water.”
All righty then. I don’t think the others were liking Smith’s idea of “righteousness”, aka polygamy.
