The failure of our ministers to exercise all the organs of the body proportionately causes some organs to become worn, while others are weak from inaction. If wear is left to come almost exclusively upon one organ or set of muscles, the one most used must become overwearied and greatly weakened. Each faculty of the mind, and each muscle, has its distinctive office, and all are required to be equally exercised in order to become properly developed and to retain healthful vigor. Each organ has its work to do in the living organism.

[Nogle af vore prædikanters undladelse af at gøre brug af alle legemets organer i det rigtige forhold, medfører at enkelte organer bliver udslidt, mens andre er svage som følge af uvirksomhed. Dersom sliddet næsten udelukkende går ud over et enkelt organ eller én muskelgruppe, så må de dele som bruges mest, bliver overanstrengt og stærkt svækket.
