The Predestination of the Saints/Gift of Perseverance

Moreover, the most illustrious Light of predestination and grace is the Saviour Himself—the Mediator Himself between God and men, the man Christ Jesus. And, pray, by what preceding merits of its own, whether of works or of faith, did the human nature which is in Him procure for itself that it should be this? Let this have an answer, I beg. That man, whence did He deserve this— to be assumed by the Word co-eternal with the Father into unity of person, and be the only-begotten Son of God? Was it because any kind of goodness in Him preceded? What did He do before? What did He believe? What did He ask, that He should attain to this unspeakable excellence? Was it not by the act and the assumption of the Word that that man, from the time He began to be, began to be the only Son of God? Did not that woman, full of grace, conceive the only Son of God? Was He not born the only Son of God, of the Holy Spirit and the Virgin Mary—not of the lust of the flesh, but by God's peculiar gift? Was it to be feared that as age matured this man, He would sin of free will? Or was the will in Him not free on that account? And was it not so much the more free in proportion to the greater impossibility of His becoming the servant of sin? Certainly, in Him human nature— that is to say, our nature— specially received all those specially admirable gifts, and any others that may most truly be said to be peculiar to Him, by virtue of no preceding merits of its own. Let a man here answer to God if he dare, and say, Why was it not I also? And if he should hear, “O man, who are you that repliest against God?” let him not at this point restrain himself, but increase his impudence and say, “How is it that I hear, Who are you, O man? Since I am what I hear—that is, a man, and He of whom I speak is but the same? Why should not I also be what He is? For it is by grace that He is such and so great; why is grace different when nature is common? Assuredly, there is no respect of persons with God.” I say, not what Christian man, but what madman will say this?
