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 LutherGood works are the seals and proofs of faith; for even as a letter must have a seal to strengthen the same, even so faith must have good works.
Martin LutherYour work is a very sacred matter. God delights in it, and through it, He wants to best His blessings on you. This praise of work should be inscribed on all tools, on the forehead and the faces that sweat from toiling.
Martin LutherWe refuse to believe that there are insufficient funds in the great vaults of opportunity of this nation.
