Hebrews 10 wraps up the author’s discourse on the superiority of the high priesthood of Jesus—a theme begun in chapter five. The chapter revisits how the Torah’s system of sacrifices could not take away sin as it was a shadow of things to come. The author references earlier high points of how Jesus is superior to Torah dealt with earlier. The entire second half of the chapter, though, focuses once more on the chief concern of the author—the reason he keeps telling his audience about the superiority of Jesus to the Mosaic Law—the need to keep believing the gospel so as to not “shrink back” to dependence on their obedience to law (merit-based performance) for salvation.
