...God's goal isn't simply to fill the world with people who believe the right things. It is to fill the world with people who shine with the brilliance of Christ.
Shepherding in Israel is a wonderful metaphor for this kind of discipleship. In many countries, sheep spend their lives in fenced-in pastures where they spend their time grazing and milling about. Many Christians seem to think that the Great Commission is a matter of getting sheep "into the pen"--inviting people to accept Christ, the high point of their spiritual lives. In Israel, however, where grass has difficulty growing in the arid soil, sheep must know their shepherd, following him obediently from pasture to pasture. There, shepherding is a much more active task.
It's the way to rest and safety and peace.
