Hebrews 13:20-25 The Word Of Exhortation-An Everlasting Covenant.
Our God is a God of peace. This must be understood in the context of this letter as a covenant renewal document. Peace is through the new covenant. It is no coincidence that our author describes the Lord Jesus as “that great Shepherd of the sheep, through the blood of the everlasting covenant” (v. 20 Cf. Is. 55:3; 61:8; Jer. 32:40). Ezekiel predicted that there would come one who the Lord God would establish as Shepherd, in the succession of David, and through Him a covenant of peace (34:23-25 Cf. Is. 54:10). This would be an everlasting covenant, when the Lord would also establish His sanctuary in their midst (37:24-27). Again, our author comes full circle from chapter one, seeing in the Son the succession to the throne, covenant, and promises to David, the last of the old covenant administrations of grace (II Sam. 7; I Chron. 17).
In the new covenant God’s people are perfected and made complete, including “complete in every good work to do His will” (v. 21a). This is by grace (v. 9), and “through Jesus Christ, to whom be glory forever and ever. Amen” (v. 21). Paul penned the same thoughts when he encouraged his audience to work out their “own salvation with fear and trembling; for it is God who works in you both to will and to do for His good pleasure” (Phil. 2:12b-13). This all fits in with this concluding section, of what our author himself called “the word of exhortation” (v. 22). Our author was also looking forward to joining with Timothy, someone who at that point was not free, perhaps one of those in chains. He also mentions their rulers again, sending his greetings to them, “and all the saints” (v. 24). “Grace be with you all. Amen” (v. 25).
