Of Christ's Incarnation
Luke 1:34-35
Then said Mary to the angel, How shall this be, seeing I know not a man?…


These words are the angel's answer to Mary, who, understanding the angel as speaking of a thing presently to be done before Joseph and she should come together, desires to know how she, being a virgin, should conceive. Here —

1. The angel tells her how she should " conceive and bring forth a Son," namely, by the power of the Holy Ghost, which is the power of the Highest, the Spirit of God being the true God, and so the Highest. The way of the Spirit's powerful working to this miraculous conception, is denoted by two words. One is, that the Holy Ghost should come upon her, not in an ordinary way, as in the conception of all men (Job 10:8, "Thine hands have made me, and fashioned me together round about)"; but in an extraordinary way, as on the prophets, and those that were raised to some extraordinary work. The other is, that the power of the Highest, which is infinite power, should overshadow her, to wit, make her, though a virgin, to conceive by virtue of the efficacy of infinite power, by which the world was created, when the same Spirit moved on the waters, cherished them, and framed the world.

2. He shows what should follow on this miraculous conception, namely, that the fruit of her womb, the child she should bear, should be called "the Son of God." Where the angel teaches two things.

(1) The immaculate, sinless conception of the child Jesus, that holy thing, a holy thing though proceeding from a sinful creature, not tainted with sin, as all other children are. The powerful operation of the Divine Spirit sanctified that part of the virgin's body of which the human nature of Christ was formed, so that by that influence it was separated from all impurity and defilement. So that, though it proceeded from a creature infected with original sin, there was no sin or taint of impurity in it. This was a glorious instance of the power of the Highest.

(2) He tells the virgin, that therefore, seeing that child to be thus conceived, he should be called, that is, owned to be, "the Son of God." He says not, Therefore that holy thing shall be the Son of God, for he was the Son of God before, by virtue of His eternal generation; but, therefore he shall be called, i.e., owned to be really so, and more than a man.

I. I AM TO SHOW WHO SHE WAS THAT WAS THE MOTHER OF CHRIST AS MAN. Christ as God had no mother, and as man no father. But His mother as man was Mary. She was the seed of Abraham; and so Christ was that seed of Abraham, in whom all nations were to be blessed (Galatians 3:16). She was of the tribe of Judah (Luke 3:33), and of that tribe Christ by her did spring (Hebrews 7:14). She was also of the family of David, as appears by her genealogy (Luke 3.), and therefore Christ is called the Son of David, as the Messiah behoved to be. She was, however, but a mean woman, the family of David being then reduced to a low outward condition in the world, having long before lost its flourishing state; so that our Lord "sprung up as a root out of a dry ground "(Isaiah 11:1, and Isaiah 53:2).

II. I COME TO SHOW WHAT WE ARE TO UNDERSTAND BY CHRIST'S BECOMING MAN. It implies —

1. That He had a real being and existence before His incarnation. He truly was before He was conceived in the womb of the virgin, and distinct from that being which was conceived in her. "What and if ye shall see the Son of Man ascend up where He was before?" (John 6:62). Yea, He was with His Father from all eternity, before any of the creatures came out of the womb of nothing.

2. That He actually took upon Him our nature. He assumed the entire nature of man into the unity of His Divine person, with all its integral parts and essential properties; and so was made or became a real and true man by that assumption. Hence it is said (John 1:14), "The Word was made flesh." But though Jesus Christ had two natures, yet not two persons, which was the error of Nestorius, who lived in the fourth century. Again, though "the Word was made flesh," yet it was without any confusion of the natures, or change of the one into the other: which was the heresy of the Eutychians of old, who so confounded the two natures in the person of Christ, that they denied all distinction between them. Eutyches thought that the-union was so made in the natures of Christ, that the humanity was absorbed and wholly turned into the Divine nature; so that, by that transubstantiation, the human nature had no longer being. But by this union the human nature is so united with the Divinity, that each retains its own essential properties distinct. The properties of either nature are preserved entire. It is impossible that the Majesty of the Divinity can receive any alteration; and it is as impossible that the meanness of the humanity can receive the impression of the Deity, so as to be changed into it, and a creature be metamorphosed into the Creator, and temporary flesh become eternal, and finite mount up into infinite. As the soul and the body are united, and make one person, yet the soul is not changed into the perfections of the body, nor the body into the perfections of the soul. There is a change indeed made in the humanity, by its being advanced to a more excellent union, but not in the Deity; as a change is made in the air when it is enlightened by the sun, not in the sun which communicates that brightness to the air. makes the burning bush to be a type of Christ's incarnation; the fire signifying the Divine nature, and the bush the human. The bush is a branch springing from the earth, and the fire descends from heaven. As the hush was united to the fire, yet was not hurt by the flame, nor converted into the fire, there remained a difference between the bush and the fire, yet the properties of fire shined in the bush, so that the whole bush seemed to be on fire. So in the incarnation of Christ, the human nature is not swallowed up by the Divine, nor changed into it, nor confounded with it: but they are so united, that the properties of both remain firm: two are so become one, that they remain two still; one person in two natures, containing the glorious perfections of the Divinity, and the weakness of the humanity. The fulness of the Godhead dwells bodily in Christ.

3. Christ's becoming man implies the voluntariness of this act of His in assuming the human nature.

III. I proceed to show that CHRIST WAS TRUE MAN. Being the eternal Son of God, He became man, by taking to Himself a true body and a reasonable soul. He had the same human nature which is common to all men, sin only excepted. He is called in Scripture "man," and" the Son of man, the seed of the woman, the seed of Abraham, the Son of David," &c.; which designations could not have been given unto Him, if He had not been true man. The actions and passions of His life show that He had true flesh. He was hungry, thirsty, weary, faint, &c. For certainly if the Son of God would stoop so low as to take upon Him our frail flesh, He would not omit the nobler part, the soul, without which He could not be man. We are told that Jesus increased in wisdom and stature, the one in respect of His body, the other in respect of His soul. The sufferings of His body were indeed very great; it was filled with exquisite torture and pain; but His soul sufferings were much greater, as I observed in a former discourse.

IV. I come now to show WHAT WE ARE TO UNDERSTAND BY CHRIST'S BEING CONCEIVED BY THE POWER OF THE HOLY GHOST IN THE WOMB OF THE VIRGIN MARY. To open this a little three things are to be considered here.

I. The framing of Christ's human nature in the womb of the Virgin. The matter of His body was of the very flesh and blood of the virgin, otherwise He could not haw been the Son of David, of Abraham, and Adam, according to the flesh. Indeed God might have created His body out of nothing, or have formed it of the dust of the ground, as He did the body of Adam, our original progenitor: but had He been thus extraordinarily formed, and not propagated from Adam, though He had been a man like one of us, yet He would not have ban of kin to us; because it would not have been a nature derived from Adam, the common parent of us all. It was therefore requisite to an affinity with us, not only that He should have the same human nature, but that it should flow from the same principle, and be propagated to Him. And thus He is of the same nature that sinned, and so what He did and suffered may be imputed to us. Whereas, if He had been created as Adam was, it could not have been claimed in a legal and judicial way. The Holy Ghost did not minister any matter unto Christ from His own substance. Hence Basil says, Christ was conceived, not of the substance, but by the power, not by any generation, but by appointment and benediction of the Holy Ghost.

2. Let us consider the sanctifying of Christ's human nature. I have already said that that part of the flesh of the Virgin, whereof the human nature of Christ was made, was purified and refined from all corruption by the overshadowing of the Holy Ghost, as a skilful workman separates the dross from the gold. Our Saviour was therefore called " that holy thing " (Luke 1:35). Now this sanctification of the human nature of Christ was necessary.

(1) To fit it for personal union with the Word, who, out of His infinite love, humbled Himself to become flesh, and at the same time out of His infinite purity, could not defile Himself by becoming sinful flesh.

(2) With respect to the end of His incarnation, even the redemption and salvation of lost sinners; that as the first Adam was the fountain of our impurity, so the second Adam should also be the pure fountain of our righteousness. He that needed redemption himself could never have purchased redemption for us.

3. We are to consider the personal union of the manhood with the Godhead. To clear this a little, you would know —

(1) That when Christ assumed our nature, it was not united consubstantially, so as the three persons in the Godhead are united among themselves; they all have but one and the same nature and will: but in Christ there are two distinct natures and wills, though but one person.

(2) They are not united physically, as the soul and body are united in a man: for death actually dissolves that union; but this is indissoluble. So that when His soul was expired, and His body interred, both soul and body were still united to the second person as much as ever.

(3) Nor yet is this such a mystical union as is between Christ and believers. Indeed this is a glorious union. But though believers are said to be in Christ, and Christ in them, yet they arc not one person with Him. But more positively, this assumption of which I speak is that whereby the second person in the glorious Godhead did take the human nature into a persons! union with Himself, by virtue whereof the manhood subsists in the second person, yet without confusion, as I showed already, both making but one person Immanuel, God with us. So that though there be a twofold nature in Christ, yet not a double person. Again, as it was produced miraculously, so it was assumed integrally; that is to say, Christ took a complete and perfect soul and body, with all and every faculty and member pertaining to it. And this was necessary, that thereby He might heal the whole nature of the disease and leprosy of sin, which had ceased upon and wofully infected every member and faculty of man. Christ assumed all, to sanctify all. Again, He assumed our nature with all its sinless infirmities: therefore it is said of Him (Hebrews 2:17), "In all things it behoved Him to be made like unto His brethren." But here we are to distinguish between personal and natural infirmities. Personal infirmities are such as befall particular persons, from particular causes, as dumbness, deafness, blindness, lameness, leprosies, &c. Now, it was no way necessary that Christ should assume these; but the natural ones, such as hunger, thirst, weariness, sweating, bleeding, mortality, &e. (Romans 8:3). Again, the human nature is so united with the Divine, that each nature still retains its own essential properties distinct. The glory of His Divinity was not extinguished or diminished, though it was eclipsed and obscured under the veil of our humanity; but there was no more change in the hiding of it, than there is in the body of the sun, when he is shadowed by the interposition of a cloud, And this union of the two natures in Christ is an inseparable union; so that from the first moment thereof, there never was, nor to all eternity shall there ever be, any separation of them.

V. I now proceed to show way CHRIST WAS BORN OF A VIRGIN. That Christ was to be born of a virgin, was prophesied and foretold many ages before His incarnation, as Isaiah 7:14. The Redeemer of the world behoved to be so born, as not to derive the stain of man's nature by His generation. It was most conformable to the infinite dignity of His person, that a supernatural and a Divine person be concerned as an active principle in it. By His being born of a virgin the holiness of His nature is effectually secured. Christ was an extraordinary person, and another Adam; and therefore it was necessary He should be produced a new way. Thus we may be thoroughly satisfied —

1. That Christ had a true human body; and that though He was made in the likeness of sinful flesh, He had not merely the likeness of flesh, but true flesh (Luke 24:39; Hebrews 2:14).

2. That He had reasonable soul, which was a created spirit, and that the Divine nature was not instead of a soul to Him.

3. That Christ's body was not made of any substance sent down from heaven, but of the substance of the Virgin (Galatians 4:4). He was "the seed of the woman" (Genesis 3:15), and the fruit of Mary's womb (Luke 1:42), otherwise He had not been our brother.

4. That the Holy Ghost cannot be called the Father of Christ, since His human nature was formed, not of His substance, but of that of the Virgin, by His power.

5. That though as to the nativity of Christ there was nothing as to the way of it extraordinary, but He was at the ordinary time brought forth as others (Luke 2:22, 23), and that as a general truth. "A woman, when she is in travail, hath sorrow, because her hour is come" (John 16:21), yet He was born without sin, being "that holy thing." He could not have been our Redeemer, had He not been so (Hebrews 7:26).

6. That the reason why Christ was born without sin, and the sin of Adam did not reach Him, was because He came not of Adam by ordinary generation, not by the blessing of marriage, but by a special promise after the fall.I shall conclude all with some INFERENCES.

1. Jesus Christ is the true Messiah promised to Adam as the seed of the woman, to Abraham as his seed, the Shiloh mentioned by Jacob on his deathbed, the Prophet spoken of by Moses to be raised from among the children of Israel, the Son of David, and the Son to be born of a virgin.

2. Behold the wonderful love of God the Father, who was content to degrade and abase His dear Son, in order to bring about the salvation of sinners.

3. See here the wonderful love and astonishing condescendency of the Son, to be born of a woman, in order that He might die in the room of sinners. What great love to sinners, and what unparalleled condescension was here!

4. See here the cure of our being conceived in sin, and brought forth in iniquity.

5. Christ is sensibly touched with all the infirmities that attend our frail nature, and has pity and compassion upon His people under all their pressures and burdens (Hebrews 2:17, 18).
