I found the voice of DA Carson sobering in today’s devotional reflection on Matthew 20.
… Christian leadership is profoundly self-denying for the sake of others, like Christ’s ultimate example of self-denial for the sake of others. So the church must not elevate people to places of leadership who have many of the gifts necessary to high office, but who lack this one. To lead or teach, for example, you must have the gift of leadership or teaching (Rom. 12:6–8). But you must also be profoundly committed to principled self-denial for the sake of brothers and sisters in Christ, or you are disqualified.
