Amen and amen.
This doctrine can never be discussed and taught enough. If it is lost and perishes, the whole knowledge of truth, life, and salvation is lost and perishes at the same time. But if it flourishes, everything good flourishes—religion, true worship, the glory of God, and the right knowledge of all things and of all social conditions. There is clear and present danger that the devil may take away from us the pure doctrine of faith and may substitute for it the doctrines of works and of human traditions. It is very necessary, therefore, that this doctrine of faith be continually read and heard in public.
Martin Luther, in the preface to his commentary on Galatians
