Hebrew 10:26-31

When people knowingly reject Christ's offer of salvation, they reject God's most precious gift. They ignore the leading of the Holy Spirit, the one who communicates to us God's saving love. This warning was given to Jewish Christians who were tempted to reject Christ for Judaism, but it applies to anyone and everyone who rejects Christ for another religion or deliberately turns away from God’s word.

The point is that there is no other acceptable sacrifice for sin than the death of Christ on the cross. If someone intentionally rejects the sacrifice of Christ after clearly understanding what the gospel teaches about it, then there is no way for that person to be saved, because God has not provided any other name under heaven by which we can be saved.

We must understand what the author is doing. He did not pull out a hammer to pound the struggling, suffering believers under persecution, but he has raised a red flag and sounded the alarm for those few among them who had grown arrogant toward the gospel and complacent toward the church. It was not the weak that tripped along that were in danger, but those who with intent, in calculated fashion, stood against the gospel after having once professed to be Christians. They claimed to be Christians but rejected the sufficiency of Christ. The writer pleads the last warning for them to repent before their hearts were hardened beyond remedy and they were exposed, in the words of Peter, as a dog returns to its own vomit and a sow after washing returns to wallow in the mire (II Pet. 2:22).
