This sure is matter of love; but came there any good to us by it? There did. For our conception being the root as it were, the very groundsill of our nature; that He might go to the root and repair of our nature from the very foundation, thither He went; that what had been there defiled and decayed by the first Adam, might by the Second be cleansed and set right again. That had our conception been stained, by Him therefore, primum ante omnia,to be restored again. He was not idle all the time He was an embyro all the nine months He was in the womb; but then and there He even ate out the core of corruption that cleft to our nature and us, and made both us and it an unpleasing object in the sight of God.
And what came of this? We who were abhorred by God, filii irae was our title, were by this means made beloved in Him. He cannot, we may be sure, account evil of that nature, that is now become the nature of His own Son, His now no less than ours. Nay farther, given this privilege to the children of such as are in Him, though but of one parent believing, that they are not as the seed of two infidels, but^are in a degree holy, eo ipso; and have a farther right to the laver of regeneration, to sanctify them throughout by the renewing of the Holy Ghost.O This honour is to us by the dishonour of Him; this the good by Christ an embyro.
Read it all from 1614 (emphasis mine).
