The dangers to be avoided: (i) Secularization. A clergyman may become secular by giving too much time to the study and discussion of great social problems, and also by throwing himself too freely into superficial society life. (2) He is in danger from over-occupation. Often he would do more if he did less. (3) He is in danger from depression. This may arise from lack of bodily health, or from a mind wearied by long, uninterrupted tension, or from a lack of money; and,
whatever be its cause, it unfits a minister for his great duties, and sometimes ends in despondency, which, someone has said, “is self-confidence which has failed.”
