Hebrews is the most tightly argued book in the New Testament and its warning passages (2:1-4; 4:1-2; 6:4-6; 10:26-31; 12:25-29) are terrifying to read, even when the context is understood. How much more terrifying are they when the context is removed and they are applied to other contexts! One of the harshest warnings is found in 10:26-31 and it cannot be understood without carefully understanding the context.
Hebrews has just finished his magnificent exposition on the greater priesthood of Jesus Christ, begun back in 5:1 and concluded in 10:18, with the expected actions one must take as a result of these truths in 10:19-25. He "breaks" into his exposition in 5:11-6:20 in order to grab his listener's attention in preparation for the long and difficult word (5:11). This word, found in 7:1-10:18, is bracketed by the warnings of 6:4-6 and 10:26-32. It is the latter warning that I want to focus, and in particular, the "willful sin" that is referenced in 10:26:
"For if we go on sinning willfully after receiving the knowledge of the truth, there no longer remains a sacrifice for sin, but a terrifying expectation of judgment..." (10:26-27a NASB 1995)
On the surface, this has been taken to mean continuing, willful sin as a Christian means loss of salvation. Isn't that what it says? This is where context is so critical. What is the willful sin that Hebrews is referring to? Is it any continuing sin that a believer commits? We must understand the "no sacrifice" statement first.
The phrase "there no longer remains a sacrifice for sin" in 10:26 is the same phrase that occurs in 10:18, which is the final statement of his long exposition. In short, Hebrews concludes that because the sacrifice of Christ has once and for all taken away sin, there is no longer any sacrifice for sin. This is because Christ's sacrifice is the only sacrifice and it is completed! There isn't and can never be another one. This is key to understanding this passage. The only acceptable sacrifice for my sin is Christ and it has already been accomplished.
In light of this, what does Hebrews exhort his listeners to do in 10:19-25? Draw near, hold fast, and encourage one another (10:22-24). Now for the sin. What is the concern in his book? Is it sin in general or is the entire tone of the book a concern that his listeners are considering abandoning their Christian faith due to persecution (see 10:32-36)? I think it is a fair statement to make that almost all scholars agree that Hebrews is focused on apostasy as the sin he is concerned with in his listeners. Again, context is critical. The sin in Hebrews is that of abandoning Christ, rejecting his sacrifice, and (for the listeners), returning to Judaism for salvation.
Here is the problem. If the sacrifice of Christ is the only one and therefore there is no longer any sacrifice for sin, then to leave Christ is to leave the only sacrifice! To abandon Christ means to abandon salvation. To refuse to draw near, to refuse to hold fast, to refuse to participate in community (encourage one another) is to refuse the only available means of salvation that God offers. Christ's death has forever changed how we come to God, because the veil, His flesh, has been torn so that we might have direct access to God through Him! There is no access to God except through Him. If you abandon Christ, you can't get to God!
One final observation from earlier in Hebrews: the wilderness generation of Exodus-Numbers is used as the negative example of what not to emulate in 3:7-4:13 and possibly implied in the 6:4-6 warning. The wilderness generation witnessed the ten plagues in Egypt (Ex. 7-12), crossed the Red Sea on dry land, saw God kill the entire Egyptian army (Ex. 14), ate manna from heaven every day in the wilderness and received water from multiple rocks (Ex. 16-17)), along with numerous other miracles. Yet, with their mouths full of food from heaven, they rejected the command of God to take the promised land, and as a result, were judged and died in the wilderness (Num. 13-14). For the Christian, the 'promised land' is the salvation found in Christ, and we are urged to hold fast and draw near--not to abandon or become weak in faith. Is it any surprise the very next passage in Hebrews following his long exposition and harsh warning in chapter 10 is his famous hall of faith in chapter 11? This is what he wants to inspire in his listeners! Be like these great examples of faith and draw near to Jesus! Don't abandon Christ, because He is the only all-sufficient once-for-all sacrifice for sin.
