Is propositional truth now passé?

I overheard this excellent thought on the preaching of propositional truth from Richard Phillips (here).

“It strikes me that one reason for the attacks on the "propositional" nature of biblical revelation is that academia has subtly changed our attitudes about receiving it. The quote Derek provided assumes that those who emphasize propositional truth think of themselves as scientists who coldly sift through evidence. But, biblically, the prophetic and apostolic idea is that of court testimony. (The "shaliach" background for apostleship especially supports this.) God has given "expert" testimony, with unimpeachable qualifications to support what he says. Our role is not to "study" the evidence the way a scientist does, but to respond faithfully to what we have heard. When we realize that we, not the evidence, are the ones on trial, then we may rightly emphasize the propositional content of what God has revealed in His Word.”
