So far as the stain of a guilty past can be removed from those who have contracted it; they are improvable and capable of restoration, chiefly, perhaps almost exclusively, by personal influence in some form. When a process of deterioration and decay has set in in any human soul, the germ of a more wholesome growth is introduced in nearly every case, by the transfusion and transplantation of healthier life. We test the soundness or the putrefaction of a soul by its capacity of receiving and assimilating this germ of restoration. A parent is in doubt whether a son is susceptible of renovation, whether he has not become wholly evil. He tries to bring the young man under the personal influence of a friend of noble and sympathetic character. Has his son any capacity left for being touched by such a character; of admiring its strength on one side, its softness on another? When he is in contact with it, when he perceives how pure, how self-sacrificing, how true and straight it is, is there a glow in his face, a trembling of his voice, a moisture in his eye, a wholesome self-humiliation? Or does he repel all this with a sneer and a bitter gibe? Has he that evil attribute which is possessed only by the most deeply corrupt--"they blaspheme, rail at glories"?[170] The Chaplain of a penitentiary records that among the most degraded of its inmates was one miserable creature. The Matron met her with firmness, but with a good will which no hardness could break down, no insolence overcome. One evening after prayers the Chaplain observed this poor outcast stealthily kissing the shadow of the Matron thrown by her candle upon the wall. He saw that the diseased nature was beginning to be capable of assimilating new life, that the victory of wholesome personal influence had begun. He found reason for concluding that his judgment was well founded.
