The "Go" the Lord call us to, is mostly followed by the word "Home".  Yes, we are to go into all the world and tell them about Jesus -- but we start at home, the people in our influence, and then go out to the world.  As Jesus said before he went back  to heaven, "Go tell everyone in Jerusalem, Judaea, Samaria, and the world."  You have a story of what Jesus has done for you, tell them!
