In the Sermon on the Mount, Christ lays down constitutional principles. Types and shadows are retired, and the law of spiritual life is declared. In this foundation law of the Christian system prayer assumes a conspicuous, if not a paramount, position It is not only wide, all-commanding and comprehensive in its own sphere of action and relief, but it is ancillary to all duties. Even the one demanding kindly and discriminating judgment toward others, and also the royal injunction, the Golden Rule of action, these owe their being to prayer.
