Thomas Constable points out that there are 6 different kinds of biblical preaching:
(1) kerugma, which means proclamation of the clear facts of the Christian message.
(2) didache or teaching. This was explanation and interpretation of the facts-the "so what?"
(3) paraklesis, exhortation, to apply the message.
(4) homilia, the treatment of a subject or an area of life in view of the Christian message.
(5) prophesia, the sharing of a word from God, be it new revelation or old.
(6) apologia, a defense of the Christian message in the face of hostile adversaries
