Believing that preaching remains of vital importance today, John Carrick argues that its effectiveness can be greatly enhanced if preachers make use of the patterns of communication laid down by God in Scripture for their instruction. He sees in the Bible a sacred rhetoric which the apostles and prophets, and Christ himself, used to awaken, move and persuade their hearers. While depending on the power of the Spirit, the preacher should not neglect any help which Scripture affords. Sacred rhetoric is based essentially on statements and commands (called in grammar the indicative and the imperative), which, together with exclamations and questions, are of immense significance in the preaching of the Word.
