Here’s how I summarized the theme and aim of the sermon:
In vv. 11-14 he puts the capstone on this argument. He drives it home with full force. Let me put it into the form of a theme: Because Jesus made a superior sacrifice for sins in every way we should not return to our old ways but persevere in holding fast the confession of our hope in the gospel of Jesus. I want to show you from the text four things that make the sacrifice of Jesus superior in every way, especially to Old Covenant Judaism, but essentially to every other religion or system of dealing with the human dilemma. My aim is that we will do anything but shrink back from our faith in the face of trouble rather even joyfully accept the plunder of our property (10:34) if necessary because of these things – His power in the sacrifice, His place after the sacrifice, His plan since the sacrifice, and His perfection by the sacrifice.
All hail to King Jesus who gave His body an offering for sin once for all and who now waits until all His enemies are brought under the footstool of His feet.
