The passage is doing more than talking about losing salvation. It is talking about the believer who commits apostasy (repudiates the Christian faith), for whom 'there no longer remains a sacrifice for sins'. That's the apostasy from which there is no return, as Heb. 6:4-8 confirms.
It's sad that you think the Great Shepherd is not telling us the truth when he writes about committing apostasy in Heb 6:4-8 and Heb 10:26-27 for which there is no return to repentance.
The context of Hebrew 10:26-27, no matter how much you want it to refer to Jews, tells us that the writer to the Hebrews is writing to Christians. We know this from these verses in Ch. 10:
Heb 10:10, By that will we have been sanctified through the offering of the body of Jesus Christ once for all. (ESV)
Heb 10:15, And the Holy Spirit also bears witness to us....
Heb 10:19, Therefore, brothers and sisters since we have confidence to enter the holy places by the blood of Jesus,
Heb 10:22, Let us draw near with a true heart in full assurance of faith
.
Heb 10:23, Let us hold fast the confession of our hope without wavering

Heb 10:24, And let us consider how to stir up one another to love and good works.
Heb 10:25, Not neglecting to meet together as is the habit of some, but encouraging one another.
Heb 10:26, 'For if we go on sinning deliberately

Ham, you know that that is a false statement that I only have conversations with those who agree with me. I have conversed with many on this forum over years who have disagreed with me. Please quit lying about the content of my conversations on CF.
You don't seem to like the challenges that I am making to your view on apostasy.
