We’ve already seen that at the heart of the Great Comission is the command to make disciples of all nations. That is achieved by going, baptizing and teaching them to obey everything Jesus has commanded.
Go means go, not “as you happen to go about your normal life”. Go means crossing geographic, cultural and linguistic barriers. How else are the nations to be discipled?
We may argue that not everyone is called to make disciples cross-culturally. We may say that making disciples begins in Jerusalem and then spreads out to the ends of the earth (Acts 1:8). But however uncomfortable it makes us feel, in this passage, Jesus means what he says — go make disciples of all nations. Don’t stop with your own back yard.
All authority in heaven and on earth has been given to the risen Lord. The mandate is universal.
It may not be easy, but it is clear.
