Elder Bruce R. McConkie taught that all prophets are types of Christ: "A prophet is one who has a testimony of Jesus, who knows by revelations of the Holy Ghost to his soul that Jesus Christ is the Son of God. In addition to this divine knowledge, many of them lived in special situations of did particular things that singled them out as types and patterns and shadows of that which was to be in the life of Him who is the Lord." (The Promised Messiah, pg 448)
President Brigham Young taught that "Joseph was foreordained to be the temporal savior of his father's house and the seed of Joseph are ordained to be the spiritual and temporal saviors of all the house of Israel in the latter days." (Journal of Discourses 7:290)
Regarding the above quote by Brigham Young, How is the church spiritually doing to the House of Israel what Joseph temporally did for his family anciently?

The Life of Joseph typifies the life and mission of Jesus Christ
1. Joseph was the favored son of his father; so was Jesus (see Genesis 37:3; Matthew 3:17).
2. Joseph was rejected by his brothers, the Israelites, as was Jesus (see Genesis 37:4; John 1:11; Isaiah 53:3; 1 Nephi 19:13–14).
3. Joseph was sold by his brothers into the hands of the Gentiles, just as Jesus was (see Genesis 37:25–27; Matthew 20:19).
4. Judah, the head of the tribe of Judah, proposed the sale of Joseph. Certain leaders of the Jews in Jesus’ day turned Jesus over to the Romans. Judas (the Greek spelling of Judah) was the one who actually sold Jesus. (See Genesis 37:26; Matthew 27:3.)
5. Joseph was sold for twenty pieces of silver, the price of a slave his age. Christ was sold for thirty pieces of silver, the price of a slave His age. (See Genesis 37:28; Matthew 27:3; Exodus 21:32; Leviticus 27:5.)
6. In their very attempt to destroy Joseph, his brothers actually set up the conditions that would bring about their eventual temporal salvation—that is, Joseph, by virtue of being sold, would become their deliverer. Jesus, by His being given into the hands of the Gentiles, was crucified and completed the atoning sacrifice, becoming the Deliverer for all mankind.
7. Joseph began his mission of preparing salvation for Israel at age thirty, just as Jesus began His ministry of preparing salvation for the world at age thirty (see Genesis 41:46; Luke 3:23).
8. When Joseph was finally raised to his exalted position in Egypt, all bowed the knee to him. All will eventually bow the knee to Jesus. (See Genesis 41:43; D&C 88:104.)
9. Joseph provided bread for Israel and saved them from death, all without cost. Jesus, the Bread of Life, did the same for all men. (See Genesis 42:35; John 6:48–57; 2 Nephi 9:50.)
