Hebrews Chapter 10 is specifically about the animal sacrifices that the people in the OT would do, “But in those sacrifices there is a remembrance again made of sins every year. For it is not possible that the blood of bulls and of goats should take away sins. (10:3-4)”, also how Jesus is now our sacrifice for sin, “But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God; (10:12)”. Verse 26 “For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,” is saying that if you sin knowing that what you are doing is sinful, then there is no sacrifice that you can do, such as slaying an animal on the altar. People in the OT used to do animal sacrifices after they would sin to try to have the Lord not be as angry with them, Paul is saying that now we do not do that, so if you sin then there is no animal you can slay to please the Lord. Now of course that is not saying that it is okay to sin because as he says in Chapter 12, “For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth. (12:6)”, so if you sin you are not no longer a child of God, but since you are a child of God then God will chastise you for your sinning, like how if a child breaks the rules in the house their parents should give them a spanking, not disown their child and throw them into a furnace of fire. Verse 26 also then means that God also expects more out of us now than he did with the people in the OT, and will punish us more when we do sin.
