Jesus said to take the Gospel to the whole world. The original apostles and the emerging church did just that in their time. They did it without any of the technology we have. They did it by each believer sharing with their friends and neighbors. We seem to have largely left the job to the clergy, to the preachers, and wonder why it seems so few of our friends know about or are interested in Jesus. Pastor Mark is teaching that just like in the first century, the Gospel is spread by individual believers living Christlike lives in front of their friends and then sharing the Truth with them.
