The zeal of the Church for the glory of her King will not rise until pastors and mission leaders and seminary teachers make much more of the King. When the glory of God himself saturates our preaching and teaching and conversations and writings, and when he predominates above our talk of methods and strategies and psychological buzzwords and cultural trends, then the people might begin to feel that he is the central reality of their lives and that the spread of his glory is more important than all their possessions and plans.
