John Frame

The idea that God communicates with human beings in personal words pervades all of Scripture, and it is central to every doctrine of Scripture. If God has, in fact, not spoken to us personally, then we lose any basis for believing in salvation by grace, in judgment, in Christ’s atonement—indeed, for believing in the biblical God at all. Indeed, if God has not spoken to us personally, then everything important in Christianity is human speculation and fantasy.
