There is no sacrifice available at all for those who do not continue in the faith abiding in Him truly it is not available for anyone who is not saved after they die.
Hebrews 10:26-39
26 For if we sin wilfully after we have received the knowledge of the truth, there no longer remains a sacrifice for sins, 27 but a certain fearful expectation of judgment, and fiery indignation which will devour the adversaries. 28 Anyone who has rejected Moses’ law dies without mercy on the testimony of two or three witnesses. 29 Of how much worse punishment, do you suppose, will he be thought worthy who has trampled the Son of God underfoot, counted the blood of the covenant by which he was sanctified a common thing, and insulted the Spirit of grace? 30 For we know Him who said, “Vengeance is Mine, I will repay,” [g]says the Lord. And again, “The Lord will judge His people.” 31 It is a fearful thing to fall into the hands of the living God. 32 But recall the former days in which, after you were [h]illuminated, you endured a great struggle with sufferings: 33 partly while you were made a spectacle both by reproaches and tribulations, and partly while you became companions of those who were so treated; 34 for you had compassion on me in my chains, and joyfully accepted the plundering of your [j]goods, knowing that you have a better and an enduring possession for yourselves [k]in heaven. 35 Therefore do not cast away your confidence, which has great reward. 36 For you have need of endurance, so that after you have done the will of God, you may receive the promise:
37 “For yet a little while,
And He[l] who is coming will come and will not [m]tarry.
38 Now the[n] just shall live by faith;
But if anyone draws back,
My soul has no pleasure in him.”
39 But we are not of those who draw back to [o]perdition, but of those who believe to the saving of the soul.
The below passage shows to depart from faith the true teaching to do so willingly when one knows it and not to repent would be crucifying Christ again for themselves but such crucifixion is temporary and does not atone for their sin He would not need to because if He did He would pay for their sin already when He was crucified.
Hebrews 6
New King James Version
The Peril of Not Progressing
6 Therefore, (A)leaving the discussion of the elementary principles of Christ, let us go on to [a]perfection, not laying again the foundation of repentance from (B)dead works and of faith toward God, 2 (C)of the doctrine of baptisms, (D)of laying on of hands, (E)of resurrection of the dead, (F)and of eternal judgment. 3 And this we will do if God permits.
4 For it is impossible for those who were once enlightened, and have tasted the heavenly gift, and have become partakers of the Holy Spirit, 5 and have tasted the good word of God and the powers of the age to come, 6 [c]if they fall away, to renew them again to repentance, since they crucify again for themselves the Son of God, and put Him to an open shame.
