Isa 6, 8 Whom shall I send? Who will go for us?

(Isa 6, 8) Whom shall I send? Who will go for us?

[8] Then I heard the voice of the Lord saying, "Whom shall I send? Who will go for us?" "Here I am," I said; "send me!"

(CCC 2543) "But now the righteousness of God has been manifested apart from law, although the law and the prophets bear witness to it, the righteousness of God through faith in Jesus Christ for all who believe" (Rom 3:21-22). Henceforth, Christ's faithful "have crucified the flesh with its passions and desires"; they are led by the Spirit and follow the desires of the Spirit (Gal 5:24; cf. Rom 8:14, 27).
