And whosoever of you will be the chiefest, shall be servant of all.  (Mark 10:44)

It is hard to find a great leader.  Some people want to look great in the eyes of people by taking pride of what they presently do.  They want to appear deserving for whatever position there is in leadership and do not accept corrections or criticisms. 

On the other hand, Jesus spoke about the principle of becoming a great leader that one must have an attitude of humility, faith, and servanthood.  

And the apostles said unto the Lord, Increase our faith. And the Lord said, If ye had faith as a grain of mustard seed, ye might say unto this sycamine tree, Be thou plucked up by the root, and be thou planted in the sea; and it should obey you. But which of you, having a servant plowing or feeding cattle, will say unto him by and by, when he is come from the field, Go and sit down to meat? And will not rather say unto him, Make ready wherewith I may sup, and gird thyself, and serve me, till I have eaten and drunken; and afterward thou shalt eat and drink? Doth he thank that servant because he did the things that were commanded him? I trow not. So likewise ye, when ye shall have done all those things which are commanded you, say, We are unprofitable servants: we have done that which was our duty to do. (Luke 17:5-10)

The servant mentioned in Luke 17, had done hard work already in the field when he arrived in the house.  Yet the Lord said, that after he had done all that were commanded to him, he still had to acknowledge that he is unprofitable servant, that is not worthy. There is a song based on the passage Mark 10:44 and it has a line, “If you want to be great in God’s kingdom, learn to be the servant of all”.  

If you want to be an effective leader, you must be humble to acknowledge your shortcomings, accept corrections and be willing to be helped to improve yourself, in that way, you will grow in leadership.
