Luther said, "To pray well is to study well," and we may add, to preach well.
All that is outside of the Bible, all that presumes to come into competition with it and challenges the ears of men, is but a sea, an unformed mass, of opinions and reasonings. How welcome therefore to the soul, wearied in its quest after some stable foundation on which to rest in view of death and eternity, is the immutable basis laid for faith in the infallible scriptures.
