He gave us an example to follow

There are certain people who see themselves “too big” to serve. To them, serving others is below them. They think that due to a certain stature they have attained in life, they rather ought to be served and hence don’t want to serve in any capacity. Such people are just deceiving themselves. No wonder God says, that the wisdom of this world is foolishness with Him. In certain churches, only poor people are ushers and janitors, leadership positions are for the rich. He is a CEO therefore he ought to be in a leadership position, I am a CEO of a very big company hence I cant be an Usher. This is how they think. Such people lack wisdom. As Christians, we have to be wise. If you are a CEO, you are because God put you there so if this same God says be an usher in the church, you humbly do so. Being the president of a nation doesn’t make you better than another Christian in the Kingdom. In God’s Kingdom, greatness is not measured that way. The Bible says, that “In Christ Jesus, there is no difference between bond and free”. This means that as far as Jesus is concerned, there isn’t any difference between the Christian who is a slave and one who is not. Don’t bring the ways of the world into the church. Many have and this is very disrespectful to God. There are Christians who have oppressed other Christians without even knowing. These people go on condemning other wicked people in the world when they themselves are doing the same thing in the church. You have to understand that every other Christian has the same right in his or her Father’s kingdom as you and you have no right to take from him or her what His father has for him or wants him to do in the Church. Such attitude amounts to oppression. Jesus, the King and Lord took towel and washed the feet of the Apostles and by that very act demonstrated that in the Kingdom greatness is synonymous to serving. If Jesus could wash the feet of the Apostles, who is anyone to think that he or she is too big to serve? Are you bigger than Jesus? Jesus went on after that act to state categorically that, “If I then, your lord and Master, have washed your feet; ye also ought to wash one another's feet” The operative word here is “ought”. This is not an opinion but an instruction. The master says, I went to the cross for you and have washed your feet even though I am King of kings and Lord of lords therefore none of you have an excuse for not serving one another. The truth really is that the greatest serve. Those who want to be served are the weak.
