Lu6:12ff, "He called His disciples to Himself; and from them He chose twelve whom He also named apostles: ... Peter, and Andrew ..., James and John, Philip and Bartholomew, Matthew and Thomas, James ... and Simon ..., Judas, and Judas Iscariot which also was the traitor." Lu9:1ff, "Then he called his twelve disciples together, and gave them power and authority over all devils, and to cure diseases." Mt19:28, 20:25ff, "Jesus said to them, “Assuredly I say to you, that in the regeneration, when the Son of Man sits on the throne of His glory, you who have followed Me will also sit on twelve thrones, judging the twelve tribes of Israel ... Jesus called them to Himself and said, You know that the rulers of the Gentiles lord it over them, and those who are great exercise authority over them. Yet it shall not be so among you; but whoever desires to become great among you, let him be your servant ... just as the Son of Man did not come to be served, but to serve."
People in the Biblical Church movement (house church, organic church, simple church movements, etc.) often forget that Jesus taught the twelve apostles about leading by serving right after telling them they would sit on twelve thrones judging the twelve tribes of Israel in the future. He was not telling them not to have any positional authority in the church but rather that even though he placed them in positions of authority they were not to -lord it over- people but to -act- like servants. He wasn't telling them to abdicate the positions he had placed them in, just as he did not stop being our Lord or abdicate his position of authority over us by serving us. It's the manner of leadership that was at issue, not the fact of leadership.
Likewise in John 14 when Jesus girded himself with a towel and washed the disciples feet, "You call Me Teacher and Lord, and you say well, for so I am. If I then, your Lord and Teacher, have washed your feet, you also ought to wash one another’s feet. For I have given you an example, that you should do as I have done to you. Most assuredly, I say to you, a servant is not greater than his master." Jesus did not abdicate his position as our Lord and Teacher and become a servant by serving us (function), he remained our Lord. That's the kind of leadership he wants us to imitate, a loving leader leadership not a non-leader leadership. And he didn't become the Lord by serving (function) either. He was and is the Lord in -position- regardless of how he -functions-, but he wants us to function in the power of the Holy Spirit and in love and in serving, not like the world.
He wants people in real positions of real authority who act like servants. Anyone can avoid the temptation to act like a master when he's not a master (well not everyone), but it takes the new life in Christ for a person who actually is in authority to act like a servant. The organic church movement should keep all the most extreme language we have about not controlling, or domineering, or seeking power, but serving unselfishly etc.; but apply it to elders who are actually in positions of authority. That's the real NT miracle of servant-like leadership that the Lord has accomplished by sending us his Spirit.
