The vast majority of those ensconced in high leadership positions today, particularly at the national level, have such a bankrupt lust for power that they foolishly sacrifice things of true value to gain and keep their positions. They stand in stark contrast to those whom God has called to effective leadership throughout history.
The first President of the newly-formed United States, George Washington, did not want the Presidency and had to be coaxed into accepting it. The same is true with virtually everyone in Scripture that God called into effective leadership. Virtually none was actively seeking or campaigning for a position of power. In fact, Scripture consistently paints an unflattering picture of those who were anxious for authority (i.e., Simon the magician in Acts 8.)
After his 40 years in the desert, Moses clearly did not believe he was qualified. Saul was the choice of the people of ancient Israel to be king while his successor David was the choice of God ....... and it's apparent from Scripture that becoming king was the furthest thing from David's mind and aspiration as he shepherded his father's sheep. Solomon's answer to God's offer to grant him literally anything he desired, paints him as an oddball in contrast to today's "leaders". None of the apostles that Jesus called was actively seeking that kind of position (except perhaps Judas who betrayed Him). Clearly, it was the last thing on Paul's mind when he encountered the risen Christ on the Damascus road.
There is a clear lesson here. One of the primary prerequisites for effective leadership is a reluctance to accept the position. The most qualified for leadership is usually the individual not actively seeking it and who does not believe that he/she is even qualified. Contrast that with the overwhelming majority of national "leaders" today who clamor for ever more power and prestige, and refuse to resign even when confronted with evidence of behavior that clearly disqualifies them.
Most will be shocked at who is ultimately elevated into positions of authority and responsibility in the kingdom of God. Authority in the Kingdom of God is starkly different than authority in the world.
The greatest among you shall be your servant. Whoever exalts himself will be humbled, and whoever humbles himself will be exalted. (Matt 23:11-12, ESV)
