Christian leadership is totally different to world leadership system. Jesus gave this contrast, saying that “leaders” are servants and not lording over people like the gentiles (the world) do. The world system of leadership exercises authority over their “subordinates” (top-down) but Christian leadership is bottom-up. It is not from a level of superior “position”, but a level of a servant. This is shown in Mat 20:25 - 27 :
25 Jesus called them together and said, "You know that the rulers of the Gentiles lord it over them, and their high officials exercise authority over them. 26 Not so with you. Instead, whoever wants to become great among you must be your servant, 27 and whoever wants to be first must be your slave— 28 just as the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many."
The leadership style of Jesus is given in Philippians 2:5-11
5 Your attitude should be the same as that of Christ Jesus: 6 Who, being in very nature[a] God, did not consider equality with God something to be grasped, 7 but made himself nothing, taking the very nature[b] of a servant, being made in human likeness. 8 And being found in appearance as a man, he humbled himself and became obedient to death— even death on a cross! 9 Therefore God exalted him to the highest place and gave him the name that is above every name, 10 that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, 11 and every tongue confess that Jesus Christ is Lord, to the glory of God the Father.
Christian leadership is not at all about having authority over others; in fact it is far from it. It is about serving. Having authority (not about rulership over others) is a consequence of humbling oneself to a position of servant. Jesus humbled himself, taking the form of man, though He is in the triune God so that God the Father exalted Him to the highest place and gave Him the name that is above every name(that is authority). Jesus is a good example of leadership and authority. Jesus did not demand authority, He was bestowed authority because He was exalted by Father God.
Jesus had authority over demons; Jesus taught with authority. A leader from a position of servanthood and humility speaks with authority when God backs him /exalts him. On the contrary, if a leader exercises/demands authority by force or my intimidation or sowing fear by abusing scriptures, then that authority has to be questioned. Cult leadership commonly uses fear and intimidation upon the congregration.
Be wise. Rejoice.
