While there he was called to serve a mission in England to open that nation to missionary work of the church. He later returned to England after the church settled in what is now Nauvoo, Illinois while sick with a severe illness, also afflicting his family. This second mission to England resulted in over 1500 converts and establishing the church in the island nation. He came back to Nauvoo after Joseph and Hyrum Smith were murdered in 1844. He took over as President of the Quorum of the 12 Apostles after Brigham Young replaced Joseph Smith.
Kimball trekked west and served as a counselor to Brigham Young until his death in 1868. He also served in various government positions in the territorial government of Utah and over saw the performance what members of the LDS church call saving ordinances, such as the endowment and Temple Sealings (doctrine of eternal marriage and families) in recently constructed temples such as the one in St. George and Manti Utah as well as helping these ordinances get performed for members still living in England. Kimball is remembered today as a stalwart member who stayed faithful until the end. One of his descendants , Spencer W. Kimball, became a President of the church and another, Quentin L. Cook, is currently one of the Twelve Apostles today.
