“Therefore go to all nations and make disciples. Teaching them to obey all I commanded you. And I will be with you to the very end of the age.”
Matthew 28:18-20

It involves doing something, and means getting off of your couch/ pew/ bean-bag/ bean-pew. It requires active participation. But does it mean you have to ship out to the jungles of South-east Asia?

One of the last things Jesus said to his followers was “… you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.” (Acts 1:8). Now, at the time they were hanging out in Jerusalem – so the command was to be witnesses in their home town, their local region, the neighbouring area and overseas. Which pretty much covers everyone, from your neighbours to the Wanyamwezi.
