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 LutherIt is cheering to note that [Martin] Luther (1524) did not see why schools should not be fun as well: "Now since the young must leap and jump, or have something to do, because they have a natural desire for it which should not be restrained (for it is not well to check them in everything) why should we not provide for them such schools, and lay before them such studies?
