(Isa 43, 19) See, I am doing something new!
[19] See, I am doing something new! Now it springs forth, do you not perceive it? In the desert I make a way, in the wasteland, rivers.
(CCC 711) "Behold, I am doing a new thing" (Isa 43:19). Two prophetic lines were to develop, one leading to the expectation of the Messiah, the other pointing to the announcement of a new Spirit. They converge in the small Remnant, the people of the poor, who await in hope the "consolation of Israel" and "the redemption of Jerusalem" (Cf. Zeph 2:3; Lk 2:25, 38). We have seen earlier how Jesus fulfills the prophecies concerning himself. We limit ourselves here to those in which the relationship of the Messiah and his Spirit appears more clearly.
