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 LutherThe word and works of God is quite clear, that women were made either to be wives or prostitutes.
Martin LutherThere can be no be no better instruction... than that every man who is to deal with his neighbor to follow these commandments. 'Whatsoever ye would that others should do unto you, do ye also unto them,' and 'Love thy neighbor as thyself.' If these were always followed, then everything would instruct and arrange itself; then no law books nor courts nor judicial actions would be required. All things would quietly and simply be set to rights, for everyone's heart and conscience would guide them.
Martin Luther
