That He would not send back the redeemed to the legislation of Moses -- for the law was fulfilled in Christ -- but would have them live in newness by the Word, through faith in the Son of God and love, Isaiah declared, saying:
Remember not the former things, nor bring to mind the things that were in the beginning. Behold I make new (things), which shall now spring up, and ye shall know (them). And I will make in the wilderness a way, and in the waterless place streams, to give drink to my chosen race, and to my people whom I have purchased to declare my virtues. Now a wilderness and a waterless place was at first the calling of the Gentiles: for the Word had not passed through them, nor given them the Holy Spirit to drink; who fashioned the new way of godliness and righteousness, and made copious streams to spring forth, disseminating over the earth the Holy Spirit; even as it had been promised through the prophets, that in the end of the days He should pour out the Spirit upon the face of the earth.
