Presidential Succession

The organization Jesus established during his earthly ministry was a kingdom Luke 12:31-32.

Kingdoms are generally passed on through hereditary succession rather than through committees, conclaves, conferences, contests, conventions, councils, etc. People nor their representatives generally do not vote for a new prince or king.

If the religious organization to which you belong chooses its new leader through a human process, you are justified in asking if it really is the kingdom of God on the earth.

The Church of Jesus Christ of Latter-day Saints, which we affirm is the kingdom of God on the earth, D&C 65:1-6 selects its new leader through a divine process.

Quorum of the 12 as of December 7, 2023

Men are called to the Quorum of the 12 Apostles in seniority order. At the death of the current president,  the senior apostle in seniority, not biological age, becomes the new president. Through His control over life and death, God literally decides who the next President of the Church will be. 

At any given time, some apostles may serve in the First Presidency, so there can be more than 12 living apostles. Currently, there are 15 living apostles.

1. Russell M. Nelson, age 99, is President of the Church. He was ordained an apostle on April 7, 1984.
2. Dallin H. Oaks, age 91, is President of the Quorum of the 12 and First Counselor in the First Presidency. If he is living when President Nelson dies, Elder Oaks will become the next President of the Church. He was ordained an apostle on May 3, 1984.
3. Jeffrey R. Holland, age 83, is Acting President of the Quorum of the 12. He was ordained an apostle on June 23, 1994.
4. Henry B. Eyring, age 90, is Second Counselor in the First Presidency. He was ordained an apostle on April 1, 1995.
5. Dieter F. Uchtdorf, age 83, was ordained an apostle on October 2, 2004.
6. David A. Bednar, age 71, was ordained an apostle on October 7, 2004.
7. Quentin L. Cook, age 83, was ordained an apostle on October 6, 2007.
8. D. Todd Christofferson, age 79, was ordained an apostle on April 5, 2008.
9. Neil L. Andersen, age 72, was ordained an apostle on April 4, 2009.
10. Ronald A. Rasband, age 73, was ordained an apostle on October 3, 2015.
11. Gary L. Stevenson, age 68, was also ordained an apostle on October 3, 2015, but after Elder Rasband.
12. Dale G. Renlund, age 71, was also ordained an apostle on October 3, 2015, but after Elder Stevenson.
13. Gerrit W. Gong, age 70, was ordained an apostle on March 31, 2018.
14. Ulisses Soares, age 65, was also ordained an apostle on March 31, 2018, but after Elder Gong.
15. Patrick Kearon, age 62, was ordained an apostle on December 7, 2023.
    

Is there a more elegant system of leadership training leading to presidential succession on the planet? It there is, I am not familiar with it. God controls who the senior apostle is, and that person is guaranteed to have years or even decades of experience in Church leadership.
