24When the ten heard it, they were angry with the two brothers. 25But Jesus called them to him and said, “You know that the rulers of the Gentiles lord it over them, and their great ones are tyrants over them.26It will not be so among you; but whoever wishes to be great among you must be your servant, 27and whoever wishes to be first among you must be your slave; 28just as the Son of Man came not to be served but to serve, and to give his life a ransom for many.” (Matthew 20:24-28, NRSV)
If you want to be great in the kingdom of God you must be a servant of all. Even those who would betray you. You see Jesus gave us an example of this when he washed the feet of the disciples and included in those whose feet he washed was Judas, the one wh ok handed him over.
So to do what God has called us to do we must love everyone and serve those whom we are with.
Be like Jesus and give as God gave to you.
