In the New Testament there is a fine distinction between teaching and preaching. The preacher is described as more of a “herald” (see 1 Tim. 2:7; 2 Tim. 1:11). He is to herald forth the good news, much as a town crier would enthusiastically announce good news. Good teaching will have some aspects of heralding about it, and it should involved some motivation and application. Good preaching will certainly involve teaching also, but preaching does not stop there. Preaching also involves a dynamic that strongly calls for actions, whether it is a call to repentance and faith, a call to service, or a call to carry the Gospel to others.
