Hebrews 6:9

Beloved. This is the only occurrence of this affectionate term in Hebrews.

Better things. The author has spoken sharply to his readers by way of warning and admonition. Now he soothes them. He is persuaded that they have no intention of rejecting God’s call, and yet they need admonition. They are in danger of drifting, of not giving heed to the things they have heard (eh. 2:1-3). They are in danger of repeating the mistake of Israel of old of not entering in (eh. 4:1). They have not progressed or grown satisfactorily, but are still babes when they should be full grown (eh. 5:11-14). And in the present instance he is telling them that there is real danger of their losing out. He softens this somewhat by saying that he is persuaded of better things of them, and yet he leaves the impression that their condition is serious and they must beware lest they lose out on eternal life.

That accompany salvation. Or, “that belong to salvation.” The author does not here state what these things are, but from what he has already written, the readers could not fail to know.
