No unclean thing can inherit the kingdom of God/heaven

1. Alma 11: 37
   
   

     37 And I say unto you again that he cannot save them in their sins; for I cannot deny his word, and he hath said that no unclean thing can inherit the kingdom of heaven; therefore, how can ye be saved, except ye inherit the kingdom of heaven? Therefore, ye cannot be saved in your sins.
2. Alma 40: 26
   
   

     26 But behold, an awful death cometh upon the wicked; for they die as to things pertaining to things of righteousness; for they are unclean, and no unclean thing can inherit the kingdom of God; but they are cast out, and consigned to partake of the fruits of their labors or their works, which have been evil; and they drink the dregs of a bitter cup.
3. Moses 6: 57
   
   

     57 Wherefore teach it unto your children, that all men, everywhere, must repent, or they can in nowise inherit the kingdom of God, for no unclean thing can dwell there, or dwell in his presence; for, in the language of Adam, Man of Holiness is his name, and the name of his Only Begotten is the Son of Man, even Jesus Christ, a righteous Judge, who shall come in the meridian of time.
