Matthew 20: great in the kingdom of heaven

The mother of James and John requested Jesus that their sons would be great in the kingdom of heaven. We read:

24-28 When the ten others heard about this, they lost their tempers, thoroughly disgusted with the two brothers. So Jesus got them together to settle things down. He said, “You’ve observed how godless rulers throw their weight around, how quickly a little power goes to their heads. It’s not going to be that way with you. Whoever wants to be great must become a servant. Whoever wants to be first among you must be your slave. That is what the Son of Man has done: He came to serve, not be served—and then to give away his life in exchange for the many who are held hostage.”

The great man in our world demands to be served, but in the kingdom of heaven, the greater a guy is, the more he serves. Jesus himself is the one who serves. He gave away his life in exchange of my life. If my king is the one who serves, how would dare I not to serve? Christ shows to serve and to suffer for the kingdom.
