Matthew 28:18-20: And Jesus came and said to them, “All authority in heaven and on earth has been given to me. Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.”
2. Crossing cultures is a step beyond the general mandate. This myth is that only select missionaries are called to cross cultures in order to make disciples. The rest of us should only focus on people like us, in our culture. The problem with this myth is that the actual Great Commission commands otherwise. Incredibly, Jesus gave a commandment to his mostly Jewish audience to go to a mostlyGentile people and make disciples! Jesus commanded his Jewish followers to go to all people groups (all ethnos, the Greek word for “nations”). In other words, the Great Commission itself is a mandate to cross cultures!
Furthermore, the model of Jesus mandates crossing cultures. Jesus left his home (with the Father), his culture, his language, his people (the trinity) to come to our home (earth), to our people, to speak our language, to grow up in a Jewish culture, and so on. Jesus was a cross-cultural missionary and he commands us to follow in his steps, cross any boundary, live incarnationally and make disciples.
