Luther provides what has become a famous statement about faith: “And this is the glory of faith, namely not to know where you are going, what you are doing, what you are suffering, and, after taking everything captive—perception and understanding, strength and will—to follow the bare voice of God and to be led and driven rather than to drive.”
Rittgers, Ronald Reformation Commentary on Scripture: New Testament XIII: Hebrews, James xlvii
