So the New Testament takes it for granted that Christians are aware of law, are aware of the right way, but fall short of it to their constant chagrin, pain and penitence Then there is the matter of grace. You don’t really have to preach a lot about law because everybody knows something about law. A murderer knows he ought not, a thief knows he ought not, an embezzler knows he ought not, and the adulterer knows he ought not. But you do have to preach about grace because we don’t know grace naturally. Grace is a surprising revelation. The great Judge, the great Sovereign, the great King who knows everything about me, ought to punish me.
