The 13th Article of Faith by Joseph Smith:
13 We believe in being honest, true, chaste, benevolent, virtuous, and in doing good to all men; indeed, we may say that we follow the admonition of Paul--We believe all things, we hope all things, we have endured many things, and hope to be able to endure all things. If there is anything virtuous, lovely, or of good report or praiseworthy, we seek after these things.

Doctrine and Covenants 132:
7 And verily I say unto you, that the conditions of this law are these: All covenants, contracts, bonds, obligations, oaths, vows, performances, connections, associations, or expectations, that are not made and entered into and sealed by the Holy Spirit of promise, of him who is anointed, both as well for time and for all eternity, and that too most holy, by revelation and commandment through the medium of mine anointed, whom I have appointed on the earth to hold this power (and I have appointed unto my servant Joseph to hold this power in the last days, and there is never but one on the earth at a time on whom this power and the keys of this priesthood are conferred), are of no efficacy, virtue, or force in and after the resurrection from the dead; for all contracts that are not made unto this end have an end when men are dead.

Doctrine and Covenants 132:
13 And everything that is in the world, whether it be ordained of men, by thrones, or principalities, or powers, or things of name, whatsoever they may be, that are not by me or by my word, saith the Lord, shall be thrown down, and shall not remain after men are dead, neither in nor after the resurrection, saith the Lord your God.
14 For whatsoever things remain are by me; and whatsoever things are not by me shall be shaken and destroyed.

Doctrine and Covenants 132:
15 Therefore, if a man marry him a wife in the world, and he marry her not by me nor by my word, and he covenant with her so long as he is in the world and she with him, their covenant and marriage are not of force when they are dead, and when they are out of the world; therefore, they are not bound by any law when they are out of the world.
16 Therefore, when they are out of the world they neither marry nor are given in marriage; but are appointed angels in heaven, which angels are ministering servants, to minister for those who are worthy of a far more, and an exceeding, and an eternal weight of glory.
17 For these angels did not abide my law; therefore, they cannot be enlarged, but remain separately and singly, without exaltation, in their saved condition, to all eternity; and from henceforth are not gods, but are angels of God forever and ever.

Doctrine and Covenants 132:
18 And again, verily I say unto you, if a man marry a wife, and make a covenant with her for time and for all eternity, if that covenant is not by me or by my word, which is my law, and is not sealed by the Holy Spirit of promise, through him whom I have anointed and appointed unto this power, then it is not valid neither of force when they are out of the world, because they are not joined by me, saith the Lord, neither by my word; when they are out of the world it cannot be received there, because the angels and the gods are appointed there, by whom they cannot pass; they cannot, therefore, inherit my glory; for my house is a house of order, saith the Lord God.

Doctrine and Covenants 132:
19 And again, verily I say unto you, if a man marry a wife by my word, which is my law, and by the new and everlasting covenant, and it is sealed unto them by the Holy Spirit of promise, by him who is anointed, unto whom I have appointed this power and the keys of this priesthood; and it shall be said unto them--Ye shall come forth in the first resurrection; and if it be after the first resurrection, in the next resurrection; and shall inherit thrones, kingdoms, principalities, and powers, dominions, all heights and depths--then shall it be written in the Lamb's Book of Life, that he shall commit no murder whereby to shed innocent blood, and if ye abide in my covenant, and commit no murder whereby to shed innocent blood, it shall be done unto them in all things whatsoever my servant hath put upon them, in time, and through all eternity; and shall be of full force when they are out of the world; and they shall pass by the angels, and the gods, which are set there, to their exaltation and glory in all things, as hath been sealed upon their heads, which glory shall be a fulness and a continuation of the seeds forever and ever.
20 Then shall they be gods, because they have no end; therefore shall they be from everlasting to everlasting, because they continue; then shall they be above all, because all things are subject unto them. Then shall they be gods, because they have call power, and the angels are subject unto them.
21 Verily, verily, I say unto you, except ye abide my law ye cannot attain to this glory.

Doctrine and Covenants 132:
26 Verily, verily, I say unto you, if a man marry a wife according to my word, and they are sealed by the Holy Spirit of promise, according to mine appointment, and he or she shall commit any sin or transgression of the new and everlasting covenant whatever, and all manner of blasphemies, and if they commit no murder wherein they shed innocent blood, yet they shall come forth in the first resurrection, and enter into their exaltation; but they shall be destroyed in the flesh, and shall be delivered unto the buffetings of Satan unto the day of redemption, saith the Lord God.

Doctrine and Covenants 124:
124 First, I give unto you Hyrum Smith to be a patriarch unto you, to hold the sealing blessings of my church, even the Holy Spirit of promise, whereby ye are sealed up unto the day of redemption, that ye may not fall notwithstanding the hour of temptation that may come upon you.
125 I give unto you my servant Joseph to be a presiding elder over all my church, to be a translator, a revelator, a seer, and prophet.
126 I give unto him for counselors my servant Sidney Rigdon and my servant William Law, that these may constitute a quorum and First Presidency, to receive the oracles for the whole church.

Doctrine and Covenants 132:
27 The blasphemy against the Holy Ghost, which shall not be forgiven in the world nor out of the world, is in that ye commit murder wherein ye shed innocent blood, and assent unto my death, after ye have received my new and everlasting covenant, saith the Lord God; and he that abideth not this law can in nowise enter into my glory, but shall be damned, saith the Lord.

Doctrine and Covenants 132:
66 And now, as pertaining to this law, verily, verily, I say unto you, I will reveal more unto you, hereafter; therefore, let this suffice for the present. Behold, I am Alpha and Omega. Amen.

Doctrine and Covenants 132:
60 Let no one, therefore, set on my servant Joseph; for I will justify him; for he shall do the sacrifice which I require at his hands for his transgressions, saith the Lord your God.
