10:7 Then said I, Lo, I come... to do thy will, O God. The Psalmist (Ps 40:7,8) represents Christ, who comes simply to do the will of God, completely surrendered to his will.
In the volume of the book it is written of me. In the roll of the law it is written of me; that is, there I am predicted.
10:7 In the volume of the book - In this very psalm it is written of me. Accordingly I come to do thy will - By the sacrifice of myself.
10:1-10 The apostle having shown that the tabernacle, and ordinances of the covenant of Sinai, were only emblems and types of the gospel, concludes that the sacrifices the high priests offered continually, could not make the worshippers perfect, with respect to pardon, and the purifying of their consciences. But when God manifested in the flesh, became the sacrifice, and his death upon the accursed tree the ransom, then the Sufferer being of infinite worth, his free-will sufferings were of infinite value. The atoning sacrifice must be one capable of consenting, and must of his own will place himself in the sinner's stead: Christ did so. The fountain of all that Christ has done for his people, is the sovereign will and grace of God. The righteousness brought in, and the sacrifice once offered by Christ, are of eternal power, and his salvation shall never be done away. They are of power to make all the comers thereunto perfect; they derive from the atoning blood, strength and motives for obedience, and inward comfort.
