(Only the virgin birth of Jesus to Mary could make everything work:)

Isaiah 7:14 Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel.

Matthew 1:23 Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us.

Luke 1:27 To a virgin espoused to a man whose name was Joseph, of the house of David; and the virgin’s name was Mary.

 30 And the angel said unto her, Fear not, Mary: for thou hast found favour with God.

 31 And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name JESUS.

 34 Then said Mary unto the angel, How shall this be, seeing I know not a man?

 35 And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God.

 

(Women conceive seed:)

Numbers 5:28 And if the woman be not defiled, but be clean; then she shall be free, and shall conceive seed.

Hebrews 11:11 Through faith also Sara herself received strength to conceive seed, and was delivered of a child when she was past age, because she judged him faithful who had promised.

Ruth 4:13 So Boaz took Ruth, and she was his wife: and when he went in unto her, the LORD gave her conception, and she bare a son.

(This is how we are conceived:)

Job 14:4 Who can bring a clean thing out of an unclean? not one.

Job 25:4 How then can man be justified with God? or how can he be clean that is born of a woman?

Psalm 51:5 Behold, I was shapen in iniquity; and in sin did my mother conceive me.

(But clearly Jesus is clean, holy, and without sin:)

Hebrews 4:15 For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin.

Hebrews 7:26 For such an high priest became us, who is holy, harmless, undefiled, separate from sinners, and made higher than the heavens;

(Either this miracle, of the virgin birth, is either a divine "invitro fertilization"

Or Mary conceived seed, not by human sperm from a man-child of Adam, but she conceived seed by the Holy Ghost.

Which would mean that Mary is either the surrogate mother or the actual mother of Jesus.

Mary is the actual mother of Jesus:)

Genesis 3:15 And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.

Romans 1:3 Concerning his Son Jesus Christ our Lord, which was made of the seed of David according to the flesh;

Hebrews 2:16 For verily he took not on him the nature of angels; but he took on him the seed of Abraham.

Galatians 4:4 But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law,

John 7:42 Hath not the scripture said, That Christ cometh of the seed of David, and out of the town of Bethlehem, where David was?

Psalm 132:11 The LORD hath sworn in truth unto David; he will not turn from it; Of the fruit of thy body will I set upon thy throne.

Psalm 89:3 I have made a covenant with my chosen, I have sworn unto David my servant,

 4 Thy seed will I establish for ever, and build up thy throne to all generations. Selah.

Revelation 22:16 I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, and the bright and morning star.

Romans 9:5 Whose are the fathers, and of whom as concerning the flesh Christ came, who is over all, God blessed for ever. Amen.

Acts 2:30 Therefore being a prophet, and knowing that God had sworn with an oath to him, that of the fruit of his loins, according to the flesh, he would raise up Christ to sit on his throne;

Acts 13:22 And when he had removed him, he raised up unto them David to be their king; to whom also he gave testimony, and said, I have found David the son of Jesse, a man after mine own heart, which shall fulfil all my will.

 23 Of this man’s seed hath God according to his promise raised unto Israel a Saviour, Jesus:

II Timothy 2:8 Remember that Jesus Christ of the seed of David was raised from the dead according to my gospel:

Galatians 3:16 Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.

(The promise to David that his house would be established forever and that his throne would be established forever:)

II Samuel 7:12 And when thy days be fulfilled, and thou shalt sleep with thy fathers, I will set up thy seed after thee, which shall proceed out of thy bowels, and I will establish his kingdom.

 13 He shall build an house for my name, and I will stablish the throne of his kingdom for ever.

 14 I will be his father, and he shall be my son. If he commit iniquity, I will chasten him with the rod of men, and with the stripes of the children of men:

 15 But my mercy shall not depart away from him, as I took it from Saul, whom I put away before thee.

 16 And thine house and thy kingdom shall be established for ever before thee: thy throne shall be established for ever.

Psalm 89:35 Once have I sworn by my holiness that I will not lie unto David.

 36 His seed shall endure for ever, and his throne as the sun before me.

I Kings 9:5 Then I will establish the throne of thy kingdom upon Israel for ever, as I promised to David thy father, saying, There shall not fail thee a man upon the throne of Israel.

(The promise David's throne would be established forever to be through Solomon:)

I Chronicles 22:9 Behold, a son shall be born to thee, who shall be a man of rest; and I will give him rest from all his enemies round about: for his name shall be Solomon, and I will give peace and quietness unto Israel in his days.

 10 He shall build an house for my name; and he shall be my son, and I will be his father; and I will establish the throne of his kingdom over Israel for ever.

(It would be David's physical seed that the LORD would cause to sit on throne:)

Psalm 132:11 The LORD hath sworn in truth unto David; he will not turn from it; Of the fruit of thy body will I set upon thy throne.

(But then Coniah, David's royal seed down from Solomon, was promised that none of his seed, the continuation of the royal seed of David down from Solomon, would ever sit upon the throne of David)

Jeremiah 22:24 As I live, saith the LORD, though Coniah the son of Jehoiakim king of Judah were the signet upon my right hand, yet would I pluck thee thence;

 28 Is this man Coniah a despised broken idol? is he a vessel wherein is no pleasure? wherefore are they cast out, he and his seed, and are cast into a land which they know not?

 29 O earth, earth, earth, hear the word of the LORD.

 30 Thus saith the LORD, Write ye this man childless, a man that shall not prosper in his days: for no man of his seed shall prosper, sitting upon the throne of David, and ruling any more in Judah.

(But now, how could the promise that the seed of David's house and David's throne would be established forever,

when God stopped the royal seed at Coniah, from ever sitting on David's throne again?

Only the virgin birth could bring this about.

First, the promise of David's seed being established forever was kept by Mary being a direct descendant of David,

not of the royal seed line through Solomon, but of the line of Nathan, not the prophet, one of the other sons of David and Bathsheba.

Then secondly, the promise that David's throne would be established forever, was kept by Joseph being of the seed royal down through Solomon,

the right of the throne belonged to Joseph by his royal lineage, given by Matthew,

but no seed of Coniah, including Joseph, and any of Joseph's seed, could ever sit on David's throne.

But since Jesus was not Joseph's seed, only Mary's, Jesus became Joseph's firstborn by right of adoption,

and as Joseph's adopted firstborn, the right of the throne was given to Jesus, without violating the promise to Coniah.

But since Jesus was Mary's son, and thereby of the seed of David through Nathan, both promises to David would still be kept,

but only by the virgin birth of Jesus - nothing else could work and still keep the scriptures.)

(Joseph's lineage down from David through Solomon, the royal seed, is given in Matthew 1:)

Matthew 1:1 The book of the generation of Jesus Christ, the son of David, the son of Abraham.

 2 Abraham begat Isaac; and Isaac begat Jacob; and Jacob begat Judas and his brethren;

 3 And Judas begat Phares and Zara of Thamar; and Phares begat Esrom; and Esrom begat Aram;

 4 And Aram begat Aminadab; and Aminadab begat Naasson; and Naasson begat Salmon;

 5 And Salmon begat Booz of Rachab; and Booz begat Obed of Ruth; and Obed begat Jesse;

 6 And Jesse begat David the king; and David the king begat Solomon of her that had been the wife of Urias;

 7 And Solomon begat Roboam; and Roboam begat Abia; and Abia begat Asa;

 8 And Asa begat Josaphat; and Josaphat begat Joram; and Joram begat Ozias;

 9 And Ozias begat Joatham; and Joatham begat Achaz; and Achaz begat Ezekias;

 10 And Ezekias begat Manasses; and Manasses begat Amon; and Amon begat Josias;

 11 And Josias begat Jechonias and his brethren, about the time they were carried away to Babylon:

 12 And after they were brought to Babylon, Jechonias begat Salathiel; and Salathiel begat Zorobabel;

 13 And Zorobabel begat Abiud; and Abiud begat Eliakim; and Eliakim begat Azor;

 14 And Azor begat Sadoc; and Sadoc begat Achim; and Achim begat Eliud;

 15 And Eliud begat Eleazar; and Eleazar begat Matthan; and Matthan begat Jacob;

 16 And Jacob begat Joseph the husband of Mary, of whom was born Jesus, who is called Christ.

(However, the lineage of Mary is given in Luke 3. One might say that it is still the line of Joseph, since Joseph is mentioned in line 23

But it is mentioned that he is the son of Heli, not Jacob as Matthew said, this is not a contradiction but either it is another man or another name for the same man.

To be another man, he could only be Joseph's father-in-law, Mary's father, since he was not Jacob, Joseph's father according to the flesh.

One might say that the generation before that have names that sound very much the same - Matthat or Matthan

But the generations preceding that are totally different - Levi or Eleazar, Melchi or Eliud, Janna or Achim, and many more.

The most convincing is that Matthew mentioned that Joseph came down from the royal line: Solomon, Roboam, Abia, Asa, Josaphat, down through Coniah, i.e. Jeconias

But in Luke 3:31 the line goes back through a different line, ending with Nathan, which was another son of David.

One might say that in both lineages there is a Salathiel and Zorobabel, that they must be the same

But ancestors of Salathiel are completely different in the two lineage accounts, and the descendants of Zorobabel are completely different in the two lineage accounts

They are a completely different father son pair, with the same names, in two different Davidic lineages.)

(This also occurred in a lineage mentioned in I Chronicles:)

I Chronicles 6:7 Meraioth begat Amariah, and Amariah begat Ahitub,

  8 And Ahitub begat Zadok, and Zadok begat Ahimaaz,

(and then a few generations later:)

I Chronicles 6:11 And Azariah begat Amariah, and Amariah begat Ahitub,

  12 And Ahitub begat Zadok, and Zadok begat Shallum,

(The exact same three names, in the exact same order, but some generations apart.

So, it is equally as likely that two names that are the same show up in the two different David linages, even in the same order.)

(Since the Luke account is the Davidic lineage of Mary through Nathan

But since only the men are mentioned in that lineage, that it is Mary's father, mentioned as Joseph's father-in-law, seemingly not uncommon in Jewish ancestries.)

Luke 3:23 And Jesus himself began to be about thirty years of age, being (as was supposed) the son of Joseph, which was the son of Heli,

 24 Which was the son of Matthat, which was the son of Levi, which was the son of Melchi, which was the son of Janna, which was the son of Joseph,

 25 Which was the son of Mattathias, which was the son of Amos, which was the son of Naum, which was the son of Esli, which was the son of Nagge,

 26 Which was the son of Maath, which was the son of Mattathias, which was the son of Semei, which was the son of Joseph, which was the son of Juda,

 27 Which was the son of Joanna, which was the son of Rhesa, which was the son of Zorobabel, which was the son of Salathiel, which was the son of Neri,

 28 Which was the son of Melchi, which was the son of Addi, which was the son of Cosam, which was the son of Elmodam, which was the son of Er,

 29 Which was the son of Jose, which was the son of Eliezer, which was the son of Jorim, which was the son of Matthat, which was the son of Levi,

 30 Which was the son of Simeon, which was the son of Juda, which was the son of Joseph, which was the son of Jonan, which was the son of Eliakim,

 31 Which was the son of Melea, which was the son of Menan, which was the son of Mattatha, which was the son of Nathan, which was the son of David,

 32 Which was the son of Jesse, which was the son of Obed, which was the son of Booz, which was the son of Salmon, which was the son of Naasson,

 33 Which was the son of Aminadab, which was the son of Aram, which was the son of Esrom, which was the son of Phares, which was the son of Juda,

 34 Which was the son of Jacob, which was the son of Isaac, which was the son of Abraham, which was the son of Thara, which was the son of Nachor,

 35 Which was the son of Saruch, which was the son of Ragau, which was the son of Phalec, which was the son of Heber, which was the son of Sala,

 36 Which was the son of Cainan, which was the son of Arphaxad, which was the son of Sem, which was the son of Noe, which was the son of Lamech,

 37 Which was the son of Mathusala, which was the son of Enoch, which was the son of Jared, which was the son of Maleleel, which was the son of Cainan,

 38 Which was the son of Enos, which was the son of Seth, which was the son of Adam, which was the son of God.

(Nathan and Solomon are both sons of David and Bathsheba:)

II Samuel 5:14 And these be the names of those that were born unto him in Jerusalem; Shammua, and Shobab, and Nathan, and Solomon,

I Chronicles 3:5 And these were born unto him in Jerusalem; Shimea, and Shobab, and Nathan, and Solomon, four, of Bathshua the daughter of Ammiel:

I Chronicles 14:4 Now these are the names of his children which he had in Jerusalem; Shammua, and Shobab, Nathan, and Solomon,

Zechariah 12:12 And the land shall mourn, every family apart; the family of the house of David apart, and their wives apart; the family of the house of Nathan apart, and their wives apart;

(Only the virgin birth of Jesus to Mary, who was espoused to Joseph, could make everything work.)
