This is a text that raises fascinating questions. And I think it is right and good to ask questions of involved texts. Asking the right questions is very much like what Paul must have meant when he wrote to young Timothy - 2 Timothy 2:7 - "Think over what I say, for the Lord will give you understanding in everything."
Paul obviously knew Timothy would read his letter. But he's not asking Timothy to read his letter. He's asking him to think about his letter because God works as readers think. And there's no better way to pull the authors intended meaning from a text than to ask questions of that text.
Actually, we have proof of this - Spirit inspired proof - right in these opening verses of Hebrews chapter ten. Look at our writer's method of deepening understanding in verse 2 - "Otherwise, would they not have ceased to be offered, since the worshipers, having once been cleansed, would no longer have any consciousness of sins?"
Note the question mark at the end of that verse. This is our writer's way of making his readers do more than just read. This is our writer's way of forcing application and pulling out implications from what these readers are reading. In Paul's words to Timothy, he's making them "think over what he is saying."
