Hebrews 2:1. The first chapter has asserted the fame of the Son when come into the world. As the exceeding glory of the speaker is recognized, it becomes the hearers to take earnest heed to what is said. To make a profession of hearing and afterward neglect the great salvation announced by the Lord by going back to Judaism was fatal. The snare was not merely letting slip the things they had heard, but the far greater danger of the professors themselves slipping from Christian ground by returning to Judaism. This would be apostasy. (See JND translation.)
Throughout the epistle the writer is addressing Jews who have made a profession of Christianity, and among them he includes himself. In the first chapter he says, God has “spoken unto us”; here he says, “We ought to give the more earnest heed.” Others have pointed out that in this epistle the church is not addressed as such, but rather believers individually. They are viewed as having made a profession which is presumed to be real unless, by turning back from Christ, it is proved to be merely outward.
Hebrews 2:2. God maintained the authority of the word communicated by angels by attaching a just punishment to every transgression of and disobedience to that word. How much more will God maintain the authority of the word of the Son. If there was no escape from the consequences of disobeying the law given by the disposition of angels, still less will there be any escape for the one who, having nominally made a profession of Christianity, treats the word of Christ with indifference and gives it up to return to Judaism.
Hebrews 2:3-4. In its strict interpretation, the salvation of which the writer speaks is not the gospel of the grace of God as presented today; nor does it exactly contemplate the indifference of a sinner to the Gospel. Yet an application in this sense may surely be made, for it must ever be true that there can be no escape for the one who finally neglects the gospel. Here it is the salvation which was preached by the Lord to the Jews, by which a way of escape was opened to the believing remnant from the judgment about to fall on the nation. This salvation was afterward preached by Peter and the other apostles in the early chapters of the Acts, when they said, “Save yourselves from this untoward generation.” This testimony was borne witness to by God with “signs and wonders” and “divers miracles.” This gospel of the kingdom will again be preached after the church has been completed.
To have broken the law was solemn; to turn from the preaching of grace is worse; but most solemn of all is to profess to believe the word, and afterward treat it with contempt by giving it up and turning back to Judaism or some other religion. This is apostasy; and for the apostate Scripture holds out no hope.
