Servant leadership is a concept people of faith can embrace. As a Christian, I know that leaders are expected to lead by example. I used the example of Christ washing the feet of his disciples during The Last Supper as one example of servant leadership.
However, the Google Alert app clued me in to one more. This source pinpointed the passage found in Matthew 20 where Christ warns the disciples not to be like leaders who engage in conspicuous displays of piety and authority.
Christ seems to be aware that leadership positions attract a fair share of people with big egos, so he feels that is necessary to say that a true leader must be a servant who is willing to be humble and make sacrifices in the interest of his or her followers.
