In the final analysis, the ultimate authority for preaching is the authority of the Bible as the Word of God. Without this authority, the preacher stands naked and silent before the congregation and the watching world. If the Bible is not the Word of God, the preacher is involved in an act of self-delusion or professional pretension. Standing on the authority of Scripture, the preacher declares a truth received, not a message invented. The teaching office is not an advisory role based in religious expertise but a prophetic function whereby God speaks to His people.
