Real heroes would have to include any who make a great sacrifice for others. That would include soldiers, firefighters, those police officers who truly do protect and serve, missionaries and volunteers who serve the needy. A one-time sacrifice is to be praised, but also a lifetime of sacrifice. In Mark 8:27-38 Jesus defined some ingredients of what it takes to be a true hero. Denying self, taking up our cross and losing our life for the gospel. On one university campus a theology professor asked his students to look out the window at the school of medicine and the school of law. He then said that those graduating from those schools would make many times more than a pastor, but serving Christ is where the true riches are. We are all called to be part of that heroic mission.
