But If Not...

 I'm looking for a pattern in past scriptures that gives both the possible blessing or the possible curse based on repentance or not. I'm wondering how many times the "but if not" part came to pass. What if ALL the "but if not's" have come to pass. Then maybe we are being told the "but if not's" for our day also will happen...

1. 3 Nephi 10:6 O ye house of Israel whom I have ^aspared, how oft will I gather you as a hen gathereth her chickens under her wings, if ye will repent and ^breturn unto me with full purpose of ^cheart. 

  7 But if not, O house of Israel, the places of your dwellings shall become ^adesolate until the time of the fulfilling of the ^bcovenant to your fathers.

This one seems to refer to the Jews NOT repenting and being scattered until the foretold time of gathering (which is the covenant made with their fathers)

2. 3 Nephi 16:13 But if the Gentiles will repent and return unto me, saith the Father, behold they shall be numbered among my people, O house of Israel.
14 And I will not suffer my people, who are of the house of Israel, to go through among them, and tread them down, saith the Father.

15 But if they will not turn unto me, and hearken unto my voice, I will suffer them, yea, I will suffer my people, O house of Israel, that they shall go through among them, and shall tread them down, and they shall be as salt that hath lost its savor, which is thenceforth good for nothing but to be cast out, and to be trodden under foot of my people, O house of Israel.

This one is still future. The cross reference may be that when the "fulness of the Gentiles" is come in, it is because they have rejected the fulness of the Gospel" and don't repent so the are trodden down by those who are of the house of Israel. Who are these people? Lamanites? Ten Tribes? Jews? Muslims? Muslims do come from Jacob, whose name was Israel...

3. 3 Nephi 14:5 And it came to pass that the angel spake unto me, Nephi, saying: Thou hast beheld that if the Gentiles repent it shall be well with them; and thou also knowest concerning the covenants of the Lord unto the house of Israel; and thou also hast heard that whoso repenteth not must perish.
6 Therefore, wo be unto the Gentiles if it so be that they harden their hearts against the Lamb of God.
7 For the time cometh, saith the Lamb of God, that I will work a great and a marvelous work among the children of men; a work which shall be everlasting, either on the one hand or on the other—either to the convincing of them unto peace and life eternal, or unto the deliverance of them to the hardness of their hearts and the blindness of their minds unto their being brought down into captivity, and also into destruction, both temporally and spiritually, according to the captivity of the devil, of which I have spoken.

This one is still future. The "but if not" says the Gentiles don't repent after the "great and marvelous work" comes where all will either be "convinced" or "delivered" to the hardness of their own hearts for which they are brought into captivity and destruction temporally and spiritually.

4. 3 Nephi 21(whole chapter)

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.

12 And my people who are a remnant of Jacob shall be among the Gentiles, yea, in the midst of them as a lion among the beasts of the forest, as a young lion among the flocks of sheep, who, if he go through both treadeth down and teareth in pieces, and none can deliver.

13 Their hand shall be lifted up upon their adversaries, and all their enemies shall be cut off.

14 Yea, wo be unto the Gentiles except they repent; for it shall come to pass in that day, saith the Father, that I will cut off thy horses out of the midst of thee, and I will destroy thy chariots;

15 And I will cut off the cities of thy land, and throw down all thy strongholds;

16 And I will cut off witchcrafts out of thy land, and thou shalt have no more soothsayers;

17 Thy graven images I will also cut off, and thy standing images out of the midst of thee, and thou shalt no more worship the works of thy hands;

18 And I will pluck up thy groves out of the midst of thee; so will I destroy thy cities.

19 And it shall come to pass that all lyings, and deceivings, and envyings, and strifes, and priestcrafts, and whoredoms, shall be done away.

20 For it shall come to pass, saith the Father, that at that day whosoever will not repent and come unto my Beloved Son, them will I cut off from among my people, O house of Israel;

21 And I will execute vengeance and fury upon them, even as upon the heathen, such as they have not heard.

22 But if they will repent and hearken unto my words, and harden not their hearts, I will establish my church among them, and they shall come in unto the covenant and be numbered among this the remnant of Jacob, unto whom I have given this land for their inheritance;

23 And they shall assist my people, the remnant of Jacob, and also as many of the house of Israel as shall come, that they may build a city, which shall be called the New Jerusalem.

24 And then shall they assist my people that they may be gathered in, who are scattered upon all the face of the land, in unto the New Jerusalem.

25 And then shall the power of heaven come down among them; and I also will be in the midst.

26 And then shall the work of the Father commence at that day, even when this gospel shall be preached among the remnant of this people. Verily I say unto you, at that day shall the work of the Father commence among all the dispersed of my people, yea, even the tribes which have been lost, which the Father hath led away out of Jerusalem.

27 Yea, the work shall commence among all the dispersed of my people, with the Father to prepare the way whereby they may come unto me, that they may call on the Father in my name.

28 Yea, and then shall the work commence, with the Father among all nations in preparing the way whereby his people may be gathered home to the land of their inheritance.

29 And they shall go out from all nations; and they shall not go out in haste, nor go by flight, for I will go before them, saith the Father, and I will be their rearward.
