"Faith now means no more than passive moral acquiescence in the Word of God and the cross of Jesus. To exercise it we have only to rest on one knee and nod our heads in agreement with the instructions of a personal worker intent upon saving our soul. Such a faith as this does not perturb people. It comforts them. The face of their ego is washed and their self-confidence is rescued from discouragement."
"People must be told that the Christian religion is not something they can trifle with. the only man who can be sure he has true Bible faith is the one who has put himself in a position where he cannot go back."
"Faith as the Bible knows it is confidence in God and His Son Jesus Christ; it is the response of the soul to the divine character as revealed in the Scriptures; and even this response is impossible apart from the prior inworking of the Holy Spirit. Faith is the gift of God to a penitent soul and has nothing whatsoever to do with the senses or the data they afford. Faith is a miracle; it is the ability God gives to trust His Son, and anything that does not result in action in accord with the will of God is not faith but something else short of it."
