Prayer is the creator as well as the channel of devotion. The spirit of devotion is the spirit of prayer. Prayer and devotion are united as soul and body are united, as life and the heart are united. There is no real prayer without devotion, no devotion without prayer. The preacher must be surrendered to God in the holiest devotion. He is not a professional man, his ministry is not a profession; it is a diving institution, a divine devotion. He is devoted to God. His aim, aspirations, ambition are for God and to God, and to such prayer is essential as food is to life.
