The scriptures speak of heathen nations. Elder Orson Pratt defined the Gentile nations as those who embrace Christendom, and heathen nations as those which have not accepted Christianity (see pg. 18-19 of Prophecy Key to The Future by Duane S Crowther). The D&C 90: 9-12 says that the gospel will go to the Gentiles then Israel then the heathen nations, “That through your administration they may receive the word, and through their administration the word may go forth unto the ends of the earth, unto the Gentiles first, and then, behold, and lo, they shall turn unto the Jews. 10 And then cometh the day when the arm of the Lord shall be revealed in power in convincing the nations, the heathen nations, the house of Joseph, of the gospel of their salvation. 11 For it shall come to pass in that day, that every man shall hear the fulness of the gospel in his own tongue, and in his own language, through those who are ordained unto this power, by the administration of the Comforter, shed forth upon them for the revelation of Jesus Christ. 12 And now, verily I say unto you, I give unto you a commandment that you continue in the ministry and presidency.”
The gentile gathering is almost complete, the Jewish gathering is in preparatory stages as the Jews gather to Jerusalem to later hear the fullness of the gospel. Nations which currently we have but little influence in are yet to come. The Arabs, the Chinese, the Indian, these are a few examples of nations which we have yet to reach by and large. See Crowther’s book ‘Prophecy Key to the Future’ or my notes on such for words of the prophets indicating that we will indeed preach to these nations and find great spiritual harvest there.
Perhaps you could say some of these nations aren’t the blood of Israel, but rather that of Ishmael or some other unrelated group. Yet the truth stands that Jesus Christ is the Savior of the WORLD, and that ALL people are beloved to God. Further, we don’t know where the blood of Israel has scattered.
There was a great scattering, and we’re seeing much of it being found in places before thought unlikely. It is the work of the saints to redeem the human race by proxy temple work, all the way back to Adam. This certainly includes those living afar off, and wherever temple work is, living work of preaching the gospel is soon to follow. Remember the prophecies of temples to dot the earth. We are already building a respectful reputation among Indian scholars, many of whom admire the contribution Joseph Smith has brought to the religious community, as reported by Teryl Givens in a lecture. Africa is currently fertile grounds for the growth of the gospel, and surely that will spread to the regions of Egypt and other eastern countries. How is and isn’t the blood of Israel we know not.
Elder McConkie once said those who join the church are almost without exception the literal blood of Israel. There is also the doctrine of adoption, wherein when someone joins the church, their blood changes to include that of the blood of Israel, and they become inheritors of all promised to that household of faith. They come to know the true God, and worship him, and receive his true blessings. President Kimball suggested learning Chinese, and we might well learn Arabic, Hindi, and other languages of not only the European and American worlds, but of the eastern worlds as well, as the work of God, according to prophecy, grows to cover the earth.
President Spencer W. Kimball encouraged the saints to learn Chinese, foreseeing a great work to be done there.
