“He was in the world, and the world came into being through him; yet the world did not know him. He came to what was his own, and his own people did not accept him. But to all who received him, who believed in his name, he gave power to become children of God, who were born, not of blood or of the will of the flesh or of the will of man, but of God.” (Jn 1: 10-13)
When it comes to our physical birth, we do not have the “power to become” children of certain parents (and not of other, different parents), because we have no say in the matter. But when we are “born again” in Christ; when we’re born “of water and Spirit” (Jn 3: 3, 5), God gives us the “power to become” and to grow and to develop into a specific identity of our choice, and that is, “children of God.”
Before our Lord’s salvific death and resurrection, the “people of God” were physically born into that identity. Hence the “sign” that God chose for that identity was circumcision (Gen 17), because procreation was the be-all and end-all of their “hope.” There was yet no clear revelation of, or teaching on, resurrection, so all hopes were tied to “the will of the flesh or the will of man” to procreate. But all this changed in the Virgin Birth, which was a new “sign,” of a new covenant that God was inaugurating, which did not involve any man’s “will of the flesh,” as Isaiah prophesied: “Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son…” (Is 7: 14)
Today let me embrace the new “power” Christ brings “to all who receive Him,” regardless “of the will of the flesh or the will of man.” I choose to “become” today what He means for me to be, a child of His.
