I'm reading a book called "Compassionate Leadership". Here's a good quote:
Peter's first exhortation to Christian leaders was to shepherd the flock of God entrusted to their care (see I Pet. 5:2). The term "shepherd" is used synonymously with that of "pastor." And certainly the apostle's original readers were quite familiar with the imagery he was using in his exhortation.
In the early twenty-first century, we use this imagery to reflect the compassionate servant leader who seeks to shepherd God's people. The entire concept of serving as a leader in Christ's kingdom relates to people more than tasks. Whatever the ministry might be to which God has entrusted us, we are directed to shepherd the poeple whom God is calling us to lead. (p.30)
