"This book is the only access we have today to an infallible message from God.
Therefore authority is not intrinsic to the preacher. It is intrinsic only to God and his written word. Only the scriptures are “inspired” infallibly by God (2 Timothy 3:16). Preachers may be inspiring, but we are not inspired in this way. Our divine authority is entirely derivative. It is not in us. It is in our preaching only to the degree that what we say and mean truly expresses what God said and meant in biblical texts."
John Piper
