Luke 1:37 Commentary - Whedon's Commentary on the Old and New Testaments

37. Nothing shall be impossible Ages ago (Gen 18:14) “The LORD” had said in a similar announcement to Abraham, “Is any thing too hard for the Lord?” The angel refers to the analogous case of Elisabeth as proof to Mary that miraculous birth is an event that may now occur. The birth of an immortal being into existence is the greatest of natural events. The birth of an immortal being, without a human father, by a divine interposition, is one of the greatest of miracles. The birth of a human being from a true divine paternity, placing a God-man upon earth, is pre-eminently THE miracle of which all other miracles are but the subordinates and attendants. But all things are possible with God. To perform a contradiction is, indeed, not a possibility even with omnipotence. But then a contradiction is really nothing at all, and so does not come into the number of all things. God is fully able to suspend by miracle the laws of nature, and even reverse them all. For the laws of nature are nothing more than the ordinary action of the divine will, which God can vary just as easily as he can hold them uniform. The incarnation is just as easy a work with God as a maintenance of the ordinary laws of birth.
