We have the priesthood of Christ above and the Word of God here. The priesthood of Christ, at the Father’s right hand, applies to all our infirmities, failure, trials and weakness, but not our flesh. Our High Priest is full of tenderness and mercy (see Heb. 4:15-16). He sustains us according to the blessing, which is given us entirely out of the reach of the flesh.
His fitness for this work is the title of His person (Heb. 5:5-6), and God says He is worthy: “Thou art My Son” (Heb. 1:5). In the title for office as priest, He is forever after the order of Melchisedec.
The Word of God is living and powerful (Heb. 4:12). The believer’s life through this world is the judgment of the flesh by the Word.
