What we cannot destroy may be usefully employed
Whom we are not able to destroy we may be able to employ in holy service, is a doctrine which is not applicable to persons only, but has a distinct reference to emotions, passions, impulses, and sympathies. We are to hold ourselves in bondage, and often we are to drive ourselves to forced labour, and to become hewers of wood and stone, bearers of burdens, and indeed slaves to our higher manhood. (J. Parker, D. D.)
