I think one of the great scriptural examples of this principle is found in the Book of Mormon Chapter 2.
1 And it came to pass in that same year there began to be a war again between the Nephites and the Lamanites. And notwithstanding I being young, was large in stature; therefore the people of Nephi appointed me that I should be their leader, or the leader of their armies.Notice how Mormon accepted the responsibility to lead the armies of the Nephites and that he went forth at the head of the army. He didn’t try to lead from the back or from a place of safety, he accepted his leadership responsibility.
2 Therefore it came to pass that in my sixteenth year I did go forth at the head of an army of the Nephites, against the Lamanites; therefore three hundred and twenty and six years had passed away. (Mormon 2:1-2)
There are similar examples in others leaders in the book of Mormon. Think of the great warrior leaders like Captain Moroni (Alma 43:16), Teancum (Alma 52:33-34), and Lehi (Alma 53:2). These great leaders all knew what it means to step forward and take charge.
Leading from the front does not mean that you have to be the best at everything your team is working on, but you do have to be competent. During my time as a pilot in the Air Force I had the experience of being in a squadron where the squadron commander neglected his responsibility to maintain his flying proficiency. He quickly came to be considered the worst pilot in the squadron. Because of his lack of competence in the aircraft he lost the respect of his entire squadron. The flight schedulers would only put him up to fly with the very most proficient instructor pilots because they knew he was lacking in flying proficiency. The lesson learned from this poor leadership example is that you gain the trust of your team as you demonstrate both character and competence. When competence is lacking, trust in leadership vanishes.
