Now may the God of peace who brought again from the dead our Lord Jesus, the great shepherd of the sheep, by the blood of the eternal covenant, equip you with everything good that you may do his will, working in us that which is pleasing in his sight, through Jesus Christ, to whom be glory forever and ever. Amen. ( Hebrews 13:20-21)
At the cross of Christ, the blood was shed that brings eternal blessings to all who believe in Him: “through the blood of the everlasting covenant.” The Lord promised these eternal benefits to His people through the prophets of old. “And I will make an everlasting covenant with them, that I will not turn away from doing them good; but I will put My fear in their hearts so that they will not depart from Me . . . Moreover I will make a covenant of peace with them, and it shall be an everlasting covenant with them” (Jer 32:40 and Eze 37:26).
The blood of the new covenant of grace secures these benefits: “This cup is the new covenant in My blood, which is shed for you” (Luk 22:20). This shed blood of the Lord Jesus Christ is able to cleanse and forgive forever all who humbly trust in Him. Also, that shed blood of the new covenant (God’s new arrangement for living) supplies the adequacy we need from God for the obedient life He has called us to live: “Our sufficiency is from God, who also made us sufficient as ministers of the new covenant” (2Co 3:5-6).
