Heb 10, 10 By this "will," we have been consecrated

(Heb 10, 10) By this "will," we have been consecrated
[10] By this "will," we have been consecrated through the offering of the body of Jesus Christ once for all.

(CCC 614) This sacrifice of Christ is unique; it completes and surpasses all other sacrifices (Cf. Heb 10:10). First, it is a gift from God the Father himself, for the Father handed his Son over to sinners in order to reconcile us with himself. At the same time it is the offering of the Son of God made man, who in freedom and love offered his life to his Father through the Holy Spirit in reparation for our disobedience (Cf. Jn 10:17-18, 15:13; Heb 9:14; 1 Jn 4:10). (CCC 2824) In Christ, and through his human will, the will of the Father has been perfectly fulfilled once for all. Jesus said on entering into this world: "Lo, I have come to do your will, O God" (Heb 10:7; Ps 40:7). Only Jesus can say: "I always do what is pleasing to him" (Jn 8:29). In the prayer of his agony, he consents totally to this will: "not my will, but yours be done" (Lk 22:42; cf. Jn 4:34; 5:30; 6:38). For this reason Jesus "gave himself for our sins to deliver us from the present evil age, according to the will of our God and Father" (Gal 1:4). "And by that will we have been sanctified through the offering of the body of Jesus Christ once for all" (Heb 10:10).
