28 But we, upon whose efforts is staked the salvation of a soul, a being blessed and immortal, and destined for undying chastisement or praise, for its vice or virtue—what a struggle ought ours to be, and how great skill do we require to treat, or get men treated properly, and to change their life, and give up the clay to the spirit. For men and women, young and old, rich and poor, the sanguine and despondent, the sick and whole, rulers and ruled, the wise and ignorant, the cowardly and courageous, the wrathful and meek, the successful and failing, do not require the same instruction and encouragement.
