“But we are not of those who shrink back to destruction, but of those who have faith to the preserving of the soul.”(Hebrews 10:39, NASB)
There should be no question who are those persons of whom the writer makes this picture of contrasts.
A covenant like no other
“Not like the covenant which I made with their fathers On the day when I took them by the hand To lead them out of the land of Egypt; For they did not continue in My covenant, And I did not care for them, says the Lord.” (Hebrews 8:9, NASB)
Why anyone might want to be likened to (a) Israel en route to Canaan (b) a levitical kingdom (c) a people deported is beyond me. We should keep our parables and lessons close to the realities such as a the house built on rock.
