Believing that preaching remains a 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 hearts. 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.

Abundant examples from Scripture and from the preaching of such men as Jonathan Edwards, George Whitefield, Samuel Davies, Asahel Nettleton and Martyn Lloyd-Jones, demonstrate Carrick's case.

Insisting on the critical importance of applying, as well as explaining, the truth of Scripture, Carrick provides an effective critique of redemptive-historical preaching, arguing that this approach seriously neglect the application of the Word of God.
