The Global Church

How do you move your church from Local to Global if that's what you want for your Church.  I know not all churches are doing this, nor should they. I think the local church is very important.  We need churches who are only local, but there are also a lot of churches who are trying to go global. How can you be both local an global?  Is there middle ground? I know as a church odds are you are both anyways, but it is probably skewed one way or another. How can you get to 50/50 local and global?  Does it take an internet campus, Facebook groups or Twitter? What is the key to a Global Church?
