Through Isaiah also the Lord foretells the same things about His grace by which He fashions all men into a new creation.
Behold, I am doing a new thing;And again:
now it springs forth, do you not perceive it?
I will make a way in the wilderness
and rivers in the desert.
The wild beasts will honor me,
the jackals and the ostriches,
for I give water in the wilderness,
rivers in the desert,
to give drink to my chosen people,
the people whom I formed for myself
that they might declare my praise. (Isa 43:19-21)
By myself I have sworn;If, then, it is not possible that these shall not take place, because God’s foreknowledge is not faltering and His design not changeable, nor His will inefficacious nor His promise false, then all, without any exception, about whom these predictions were made are saved. He establishes His laws in their understanding and writes them with His finger in their hearts, so that they recognize God not through the working of human learning, but through the working of the Supreme Instructor…. In all is implanted the fear that makes them keep the commandments of God. A road is opened in the desert, the parched land is watered with streams. They who formerly did not open their mouths to praise God but like dumb and irrational animals had taken on the ferocity of beasts, now, having drunk at the fountain of the divine pronouncements, bless and praise God and recount the power and wonders of His mercy, how He chose them and adopted them to be His sons and made them heirs of the New Testament.
from my mouth has gone out in righteousness
a word that shall not return:
To me every knee shall bow,
every tongue shall swear allegiance. (Isa 45:23)
Prosper of Aquitaine, The Call of All Nations 1.9
