What is the meaning of ethnocentric?

Jesus was constantly trying to overcome prejudice. He was trying to help his group of twelve disciples realize that this world was not all about them (as individuals or as a group). The Jews had started thinking of themselves as God's favorites and possibly even his instruments of wrath as they awaited a Messiah to help them overthrow the Roman empire so that they could rule the world. Jesus talked about a different kind of kingdom where people loved their enemies, where there was no Jew or Gentile, where everyone was invited to the banquet, and where the peacemakers were blessed. He was trying to provide a completely different paradigm and worldview by which to live. Have we learned anything from his teachings?

Jesus, the "friend of sinners", enjoyed hanging out with people of many different ethnicities, social status, etc. He was trying to get his followers prepared for when he would tell them to go to Jerusalem, Judea, Samaria, and the ends of the earth. We are going to have to get past an us/them mentality if we are going to see this kingdom established that Jesus envisioned because it includes people from every people, tribe, class, education level, socio-economic status, and people group. What do you think needs to happen to see a whole kingdom of people from every nation on earth loving God and loving others?
