Hebrews 10:26-27 Sentence And Warning Section Begins.
Now our author presses his warning further to his audience, just prior to again shift to the third person and discussing the fourth part of the lawsuit (10:28-31). Here our author is still speaking his warning using ‘we’, thus including himself. Therefore there is a place for warning to true believer’s, even an apostle speaking to himself. Yet, as he will state again at the end of this section, (after the fourth section of the lawsuit), “we are not of those who draw back to perdition, but of those who believe to the saving of the soul” (v. 39). The lawsuit is against those who have sinned “wilfully,” after they had “received the knowledge of the truth” (v. 26a).
The truth is that this letter includes the last of the covenant lawsuits to be issued, because the covenant has been renewed through the Son in the new. There is no hope if one rejects the Son because, “there no longer remains a sacrifice for sins” (v. 26b). This is what it means to be “cut off” (6:6 Cf. Nu. 15:30; II Pet. 2:20). These ought to have a “fearful expectation of judgment,” but many do not, but it does serve as a warning to the faithful to avoid that course (v. 27a). It is a “fiery indignation which will devour the adversaries” (v. 27b). Essentially, those who reject the Son, reject the propitiation that He is, for the breaking of the covenantal bond (Zeph. 1:18).
