One cannot advance without faith in correct principles

D & C   84:
54 And your minds in times past have been darkened because of unbelief, and because you have treated lightly the things you have received—

55 Which vanity and unbelief have brought the whole church under condemnation.

56 And this condemnation resteth upon the children of Zion, even all.

57 And they shall remain under this condemnation until they repent and remember the new covenant, even the Book of Mormon and the former commandments which I have given them, not only to say, but to do according to that which I have written—

For the Lords Sheep who hear his voice, they will again have the opportunity  in 5 months, to come under Covenant; now that we again have a servant of the Lord on the Earth, with the High Priesthood to make such sealing and covenant in our behalf. 

3 Nephi 21:

1 And verily I say unto you, I give unto you a sign, that ye may know the time when these things shall be about to take place—that I shall gather in, from their long dispersion, my people, O house of Israel, and shall establish again among them my Zion;

2 And behold, this is the thing which I will give unto you for a sign—for verily I say unto you that when these things which I declare unto you, and which I shall declare unto you hereafter of myself, and by the power of the Holy Ghost which shall be given unto you of the Father, shall be made known unto the Gentiles that they may know concerning this people who are a remnant of the house of Jacob, and concerning this my people who shall be scattered by them;

3 Verily, verily, I say unto you, when these things shall be made known unto them of the Father, and shall come forth of the Father, from them unto you;

4 For it is wisdom in the Father that they should be established in this land, and be set up as a free people by the power of the Father, that these things might come forth from them unto a remnant of your seed, that the covenant of the Father may be fulfilled which he hath covenanted with his people, O house of Israel;

5 Therefore, when these works and the works which shall be wrought among you hereafter shall come forth from the Gentiles, unto your seed which shall dwindle in unbelief because of iniquity;

6 For thus it behooveth the Father that it should come forth from the Gentiles, that he may show forth his power unto the Gentiles, for this cause that the Gentiles, if they will not harden their hearts, that they may repent and come unto me and be baptized in my name and know of the true points of my doctrine, that they may be numbered among my people, O house of Israel;

7 And when these things come to pass that thy seed shall begin to know these things—it shall be a sign unto them, that they may know that the work of the Father hath already commenced unto the fulfilling of the covenant which he hath made unto the people who are of the house of Israel.

8 And when that day shall come, it shall come to pass that kings shall shut their mouths; for that which had not been told them shall they see; and that which they had not heard shall they consider.

9 For in that day, for my sake shall the Father work a work, which shall be a great and a marvelous work among them; and there shall be among them those who will not believe it, although a man shall declare it unto them.

10 But behold, the life of my servant shall be in my hand; therefore they shall not hurt him, although he shall be marred because of them. Yet I will heal him, for I will show unto them that my wisdom is greater than the cunning of the devil.

11 Therefore it shall come to pass that whosoever will not believe in my words, who am Jesus Christ, which the Father shall cause him to bring forth unto the Gentiles, and shall give unto him power that he shall bring them forth unto the Gentiles, (it shall be done even as Moses said) they shall be cut off from among my people who are of the covenant.
