For if we go on deliberately and willingly sinning after once acquiring the knowledge of the Truth, there is no longer any sacrifice left to atone for [our] sins [no further offering to which to look forward].
Now if we sin deliberately after we have known and accepted the truth, there can be no further sacrifice for sin for us but only a terrifying expectation of judgment and the fire of God’s indignation, which will one day consume all that sets itself against him. The man who showed contempt for Moses’ Law died without hope of appeal on the evidence of two or three of his fellows. How much more dreadful a punishment will he be thought to deserve who has poured scorn on the Son of God, treated like dirt the blood of the agreement which had once made him holy, and insulted the very Spirit of grace? For we know the one who said: ‘Vengeance is mine: I will repay’. And again: ‘The Lord will judge his people’. Truly it is a terrible thing for a man who has done this to fall into the hands of the living God!
If we give up and turn our backs on all we’ve learned, all we’ve been given, all the truth we now know, we repudiate Christ’s sacrifice and are left on our own to face the Judgment—and a mighty fierce judgment it will be! If the penalty for breaking the law of Moses is physical death, what do you think will happen if you turn on God’s Son, spit on the sacrifice that made you whole, and insult this most gracious Spirit? This is no light matter. God has warned us that he’ll hold us to account and make us pay. He was quite explicit: “Vengeance is mine, and I won’t overlook a thing” and “God will judge his people.” Nobody’s getting by with anything, believe me.
For when we intentionally commit chet b’yad ramah ["wilful sin with a high hand of defiance" BAMIDBAR 15:30] after having received the full da’as of HaEmes, there remains no longer a korban for chattoteinu,
For why now a sacrifice for sins is not left to us, that sin willfully, after that we have taken the knowing of truth. [Forsooth to us sinning willfully, after the knowing of truth taken, now an host for sins is not left.]
