Pilgrims and Strangers or World Changers?

Are we supposed to be pilgrims and strangers, or are we called to be world changers? Would pilgrims and strangers ever address themselves to the job of discipling the nations? Are pastors concerned with keeping politics out of the church, or equipping the man and woman of God to every good work? Christ's admonitions concerning salt and light are not merely descriptives, but prescriptives.
