Luke1:31And behold, you will conceive in your womb and bear a son, and you shall call His name Jesus. (34~35) But Mary said to the angel, How will this be, since I have not known a man? And the angel answered and said to her, The Holy Spirit will come upon you, and the power of the Most High will overshadow you; therefore also the holy thing which is born will be called the Son of God.
We need to see that the Lord Jesus is the Man-Savior. As the Man-Savior, He was conceived of the Holy Spirit with the divine essence. Luke tells us how the Man-Savior was conceived.
He was not conceived of a man; rather, He was conceived of the Holy Spirit with the divine essence. Here we are using the word "essence" in a strong sense to denote something even more intrinsic than nature. The essence is the intrinsic constituent of a certain substance.
The Man-Savior was conceived of the Holy Spirit not only with the divine nature but with the divine essence. In 1:27 and 31 we see that a virgin named Mary conceived in her womb and bore a Son whose name was Jesus. Because the Man-Savior was conceived of the Holy Spirit with the divine essence and was born of a human virgin with the human essence, He has two essences, the divine and the human.
With Him there is the mingling of the divine essence with the human essence. In contrast to the Man-Savior, we have only one essence, the human essence, for we were conceived of man and born of woman. Our Savior is different, for He was conceived of the Holy Spirit and born of a human virgin.
With the Holy Spirit there is the divine essence, and with the human virgin there is the human essence.
