This is a good read from Phil Johnson on his Pyromaniacs Blog
1. We are pilgrims, not tourists. We are exiles and explorers—not day trippers or vacationers. We're supposed to be ascending like first-century pilgrims on their way to a feast in Jerusalem, not wandering like the Old Testament Israelites in the wilderness.
2. We are disciples, not academics. We are working apprentices, not merely auditors of a course where we're free to skip the exams. We are interns who are responsible to put what we learn into practice; we're not imbibing information recreationally for the sake of accumulating hypothetical knowledge. Our discipleship is a vocation, not a hobby.
3. We are servants, not superstars. We're members of the church—and it's a community, not a resort. We're here to serve, not to be served. We're motivated by our concern for God's glory, not our own comfort. Our ministry is for the sake of others, not self. We're ambassadors in a foreign land, bringing a message of good news to the weary, wounded, and guilty souls who live there, offering them refuge on higher ground—and inviting them to join us on the walk to our home.
