Then comes the question of the forgiveness of sin. Is not man the creator of sin? If he creates it, he can destroy it also. If one cannot destroy, his elder brother can. The one who is capable of making is capable of destroying. He who can write with his pen can rub it with his eraser from the surface of the paper. When he cannot do it, then that personality has not yet arrived at completeness, at that perfection to which all have to come. There is no end of faults in man's life, and if they were all recorded and unerasable, life would be terrible and impossible to live. The impression of sin, in the terminology of metaphysics, may be called an illness: a mental illness, not physical. As the doctor is able to cure illness, so the doctor of the soul is able to heal. If people have said that through Christ sins are forgiven, that can be understood in this way: that love is that shower by which all is purified. No stain remains.
