Medium: The modern-day evangelist needs to use a medium by which to broadcast his or her message beyond the "hearers" of the message. Some evangelists who are into social justice issues are masters at letters to the editor or op-ed pieces for the local press. They stir up the masses and persuade the would-be bystander to take action. Others tend to use YouTube or Facebook, even Twitter and LinkedIn, with the mastery of tech wizards. You have to use some form of medium, even if it is www.youversion.com or www.gracehope.com for Christian connections.
