For it was fitting that not only the first-fruits of our nature should partake in the higher good but every man who wished it, and that a second birth should take place and that the nourishment should be new and suitable to the birth and thus the measure of perfection be attained. Through His birth, that is, His incarnation, and baptism and passion and resurrection, He delivered our nature from the sin of our first parent and death and corruption, and became the first-fruits of the resurrection, and made Himself the way and image and pattern, in order that we, too, following in His footsteps, may become by adoption what He is Himself by nature, sons and heirs of God and joint heirs with Him. He gave us therefore, as I said, a second birth in order that, just as we who are born of Adam are in his image and are the heirs of the curse and corruption, so also being born of Him we may be in His likeness and heirs of His incorruption and blessing and glory.
