Comparing Mark 1:4-9 with Luke
The contrast between the two gospels is stark in the discussion of John the Baptist.
Mark 1:4 John came, who baptized in the wilderness and preached the baptism of repentance unto remission of sins. 5 And there went out unto him all the country of Judaea, and all they of Jerusalem; and they were baptized of him in the river Jordan, confessing their sins.
Luke 3:7 He said therefore to the multitudes that went out to be baptized of him, Ye offspring of vipers, who warned you to flee from the wrath to come? 8 Bring forth therefore fruits worthy of repentance, and begin not to say within yourselves, We have Abraham to our father: for I say unto you, that God is able of these stones to raise up children unto Abraham. 9 And even now the axe also lieth at the root of the trees: every tree therefore that bringeth not forth good fruit is hewn down, and cast into the fire. 10 And the multitudes asked him, saying, What then must we do? 11 And he answered and said unto them, He that hath two coats, let him impart to him that hath none; and he that hath food, let him do likewise. 12 And there came also publicans to be baptized, and they said unto him, Teacher, what must we do? 13 And he said unto them, Extort no more than that which is appointed you. 14 And soldiers also asked him, saying, And we, what must we do? And he said unto them, Extort from no man by violence, neither accuse any one wrongfully; and be content with your wages.
In Luke they are warned about what is coming. In Mark they are confessing their sins, present tense. In Luke the axe is laid a the root, the warning is the trees that are not bearing good fruit will be cut down, in Mark they are cut down. In Luke they ask wha they must do and they are told if you have two coats you have to share, in Mark the money is gone, so no longer is this an issue, everyone is poor. Likewise the tax collectors are told to not extort people in Luke but in Mark you can't be a tax collector, in the kingdom of Antichrist you would have to take the mark to be collecting taxes or working as a soldier.
Mark 1:6 And John was clothed with camel’s hair, and had a leathern girdle about his loins, and did eat locusts and wild honey. 7 And he preached, saying, There cometh after me he that is mightier than I, the latchet of whose shoes I am not worthy to stoop down and unloose. 8 I baptized you in water; but he shall baptize you in the Holy Spirit.
Luke 3:15 And as the people were in expectation, and all men reasoned in their hearts concerning John, whether haply he were the Christ; 16 John answered, saying unto them all, I indeed baptize you with water; but there cometh he that is mightier than I, the latchet of whose shoes I am not worthy to unloose: he shall baptize you in the Holy Spirit and in fire: 17 whose fan is in his hand, thoroughly to cleanse his threshing-floor, and to gather the wheat into his garner; but the chaff he will burn up with unquenchable fire. 18 With many other exhortations therefore preached he good tidings unto the people;
Look at Mark, it is as though he is describing the people during the tribulation. They live off of bugs and honey. In Luke there are future warnings that the Lord is going to cleanse his threshingfold and gather the wheat into the barn (rapture). In Luke he is exhorting the believers, but not in Mark, no mention at all. What would be the point after the rapture.
Mark 1:9 And it came to pass in those days, that Jesus came from Nazareth of Galilee, and was baptized of John in the Jordan. 10 And straightway coming up out of the water, he saw the heavens rent asunder, and the Spirit as a dove descending upon him: 11 and a voice came out of the heavens, Thou art my beloved Son, in thee I am well pleased.
Luke 3:19 but Herod the tetrarch, being reproved by him for Herodias his brother’s wife, and for all the evil things which Herod had done, 20 added this also to them all, that he shut up John in prison. 21 Now it came to pass, when all the people were baptized, that, Jesus also having been baptized, and praying, the heaven was opened, 22 and the Holy Spirit descended in a bodily form, as a dove, upon him, and a voice came out of heaven, Thou art my beloved Son; in thee I am well pleased.
This is very weird that Luke tosses in this account about Herod putting John in prison before talking about Jesus being baptized by him. The time line on this is wonky. It is almost as though Jesus is baptized by all the evil things that Herod did. The context is that the fan is in the Lord's hand to burn up the chaff with unquenchable fire and then we see an example of the evil that John is talking about that will be burned up.
Now look at this baptism as a book end, at the beginning of the age the Spirit descends on Jesus and the testimony is this is my beloved Son in whom I am well pleased. Then at the end of the church age and again during the tribulation with the martyred saints we see the Spirit ascend with the believers during the rapture also with the testimony these are my beloved children in whom I am well pleased.
23 And Jesus himself, when he began to teach, was about thirty years of age, being the son (as was supposed) of Joseph, the son of Heli, 24 the son of Matthat, the son of Levi, the son of Melchi, the son of Jannai, the son of Joseph, 25 the son of Mattathias, the son of Amos, the son of Nahum, the son of Esli, the son of Naggai, 26 the son of Maath, the son of Mattathias, the son of Semein, the son of Josech, the son of Joda, 27 the son of Joanan, the son of Rhesa, the son of Zerubbabel, the son of Shealtiel, the son of Neri, 28 the son of Melchi, the son of Addi, the son of Cosam, the son of Elmadam, the son of Er, 29 the son of Jesus, the son of Eliezer, the son of Jorim, the son of Matthat, the son of Levi, 30 the son of Symeon, the son of Judas, the son of Joseph, the son of Jonam, the son of Eliakim, 31 the son of Melea, the son of Menna, the son of Mattatha, the son of Nathan, the son of David, 32 the son of Jesse, the son of Obed, the son of Boaz, the son of Salmon, the son of Nahshon, 33 the son of Amminadab, the son of Arni, the son of Hezron, the son of Perez, the son of Judah, 34 the son of Jacob, the son of Isaac, the son of Abraham, the son of Terah, the son of Nahor, 35 the son of Serug, the son of Reu, the son of Peleg, the son of Eber, the son of Shelah, 36 the son of Cainan, the son of Arphaxad, the son of Shem, the son of Noah, the son of Lamech, 37 the son of Methuselah, the son of Enoch, the son of Jared, the son of Mahalaleel, the son of Cainan, 38 the son of Enos, the son of Seth, the son of Adam, the son of God.
This is unique to Luke, there is no genealogy in Mark. The word "as was supposed" really stands out to me. I find all the other uses of this term interesting, people have erroneous concepts that the Lord is correcting. But if this is not Jesus genealogy, then why give it to us? There are some reasons and I will skip all that, it does fulfill prophecies that reconcile one of David's lines that was cut off permanently, and it is quite interesting why it was cut off because it sheds light on why Joseph had to go through what he had to go through to bring in this reconciliation.
But I want to skip that, I want to focus on "as was supposed". It was supposed that Jesus was a man, born like all the rest of us. Matthew shows us that Jesus was descended from Abraham and was the seed of the woman, the promised seed of Abraham. But here Jesus is not descended from Joseph and we can't understand why we are going through the whole genealogy until we get to Adam. Jesus is the second Adam and like Adam he was not born of anyone, he was born of God.
