The pietistic movements of to-day have none of the rugged reality of the New Testament about them; there is nothing about them that needs the Death of Jesus Christ; all that is required is a pious atmosphere, and prayer and devotion. This type of experience is not supernatural nor miraculous, it did not cost the passion of God, it is not dyed in the blood of the Lamb, not stamped with the hall-mark of the Holy Ghost; it has not that mark on it which makes men say, as they look with awe and wonder - “That is the work of God Almighty.” That and nothing else is what the New Testament talks about.
Oswald Chambers
