The greatest among you should be like the youngest, and the one who rules like the one who serves.

Luke 22:14-30

For I tell you, I will not eat it again until it finds fulfillment in the kingdom of God. 

After taking the cup. For I tell you I will not drink again from the fruit of the vine until the kingdom of God comes.

And he took bread, gave thanks and broke it, and gave it to them, saying, This is my body given for you; do this in remembrance of me.

This cup is the new covenant in my blood, which is poured out for you. But the hand of him who is going to betray me is with mine on the table. The Son of Man will go as it has been decreed. But woe to that man who betrays him!” They began to question among themselves which of them it might be who would do this.

A dispute also arose among them as to which of them was considered to be greatest. Jesus said to them, “The kings of the Gentiles lord it over them; and those who exercise authority over them call themselves Benefactors. But you are not to be like that. Instead, the greatest among you should be like the youngest, and the one who rules like the one who serves. For who is greater, the one who is at the table or the one who serves? Is it not the one who is at the table? But I am among you as one who serves.

Why?
Here Jesus mentioned twice that this cup and bread symbolize the blood and body of Jesus sharing with disciples. Jesus won't eat and drink it again for Jesus will leave them until the kingdom of God comes.

12 disciples did not understand Jesus was about to leave them, they disputed who was greatest among them. This situation is like most of us, we care about our position in our work and church or home.

Jesus also knew who was going to betray him, but Jesus accepted it for this was his mission and time.

Jesus serves others so we should learn Jesus as our model.

How?

Follow the way of Jesus discard his life and benefit but honestly implement God's mission. Let me be a servant to serve others as I can.
