In Romans 7, St. Paul says, "The law is spiritual." What does that mean? If the law were physical, then it could be satisfied by works, but since it is spiritual, no one can satisfy it unless everything he does springs from the depths of the heart. But no one can give such a heart except the Spirit of God, who makes the person be like the law, so that he actually conceives a heartfelt longing for the law and henceforward does everything, not through fear or coercion, but from a free heart.
Martin LutherFrom the beginning of my Reformation I have asked God to send me neither dreams, nor visions, nor angels, but to give me the right understanding of His Word, the Holy Scriptures; for as long as I have God's Word, I know that I am walking in His way and that I shall not fall into any error or delusion.
Martin LutherChrist will remain a priest and king; though He was never consecrated by any papist bishop or greased by any of those shavelings; but he was ordained and consecrated by God Himself, and by Him anointed.
Martin LutherThe authority of Scripture is greater than the comprehension of the whole of man's reason.
