Not at all. Let's not lose sight of the fact that Jesus, a human, was certifiably born on earth first.
Of course. No one has said otherwise.
The word "Son of man" refers to being a human and is used as such throughout the Bible.
Job 25
6How much less man,
that is a worm? and
the son of man, which is a worm?
Psalm 144
3LORD, what
is man, that thou takest knowledge of him!
or the son of man, that thou makest account of him!
Jesus was specific about being the "Son of Man" from heaven and not the "Son of God" from heaven.
Incorrect. Yes, the phrase is used most often of humans, but context determines meaning. Jesus is the Messiah, correct? Let's look at this Messianic passage:
Dan 7:13 “I saw in the night visions, and behold,
with the clouds of heaven there came one like a son of man, and he came to the Ancient of Days and was presented before him.
Dan 7:14 And to him was given dominion and glory and a kingdom, that all peoples, nations, and languages should serve him;
his dominion is an everlasting dominion, which shall not pass away, and his kingdom one that shall not be destroyed.
The "son of man" here is a divine being--"with the clouds of heaven there came" (see Ps 104:3 and Isa 19:1)--and not merely a man, as evidenced by "like," who resides in heaven, it would seem.
Given that Jesus is the Messiah and King, and refers to himself most often as the Son of Man, it is very clear that he is using that title as it is used in Dan 7:13.
Mat 12:8 For the Son of Man is lord of the Sabbath."
Mat 13:41 The Son of Man will send his angels, and they will gather out of his kingdom all causes of sin and all law-breakers,
Mat 16:27 For the Son of Man is going to come with his angels in the glory of his Father, and then he will repay each person according to what he has done.
Mat 16:28 Truly, I say to you, there are some standing here who will not taste death until they see the Son of Man coming in his kingdom.”
Mat 19:28 Jesus said to them, “Truly, I say to you, in the new world, when the Son of Man will sit on his glorious throne, you who have followed me will also sit on twelve thrones, judging the twelve tribes of Israel.
And, importantly:
Mat 26:63 But Jesus remained silent. And the high priest said to him, “I adjure you by the living God, tell us if you are the Christ, the Son of God.”
Mat 26:64 Jesus said to him, “You have said so. But I tell you, from now on
you will see the Son of Man seated at the right hand of Power and coming on the clouds of heaven.”
Mat 26:65 Then the high priest tore his robes and said, “
He has uttered blasphemy. What further witnesses do we need?
You have now heard his blasphemy.
Mat 26:66 What is your judgment?” They answered, “He deserves death.”
That is a clear claim to be the divine being in Dan 7:13-14, rightly deserving of blasphemy
if Jesus wasn't actually the Son of Man.
(All ESV.)
Jesus didn't pre-exist in heaven as a human.
Of course not; no one is making that argument.
Jesus didn't literally descend from heaven as the Son of Man.
Except that John1:14 and Phil 2:6-8 explicitly state otherwise. Many other passages which I have given imply the same.
That's why Jesus said so as recorded by John. Jesus said he first ascended up to heaven and then came back down. God took Jesus, temporarily. This isn't unprecedented as God also took Enoch, Elijah, and Paul knew a man who ascended up to heaven as well.
John 3
13And no man hath ascended up to heaven, but he that came down from heaven,
even the Son of man which is in heaven.
Jesus did not say he first ascended to heaven then came down. He ascends at the end of his ministry, not before. Again, context is important, as it always is. Jesus is saying that no one has been in heaven so as to understand heavenly things, except for him, which is why he understands and can teach on heavenly things.
While there are many comparisons to be made between Jesus and the manna, as Jesus pointed out in John 6, they are not identical because coming from heaven doesn't imply literally pre-existing. There is no record of manna pre-existing eternally in heaven.
Some examples. John the Baptist was sent from God, but we don't make a doctrine about John the Baptist being God or pre-existing. John 1:6.
You're completely ignoring context which results in poor reasoning. The Son is shown in Scripture to have preexisted, unlike John the Baptist. Whether or not manna preexisted in heaven is irrelevant.
Joh 6:32 Jesus then said to them, “Truly, truly, I say to you, it was not Moses who gave you the bread from heaven, but my Father gives you
the true bread from heaven.
Joh 6:33 For
the bread of God is he who comes down from heaven and gives life to the world.”
Joh 6:34 They said to him, “Sir, give us this bread always.”
Joh 6:35 Jesus said to them, “
I am the bread of life; whoever comes to me shall not hunger, and whoever believes in me shall never thirst.
Joh 6:36 But I said to you that you have seen me and yet do not believe.
Joh 6:37 All that the Father gives me will come to me, and whoever comes to me I will never cast out.
Joh 6:38 For
I have come down from heaven, not to do my own will but the will of him who sent me.
Joh 6:39 And this is the will of him who sent me, that I should lose nothing of all that he has given me, but raise it up on the last day.
Joh 6:40 For this is the will of my Father, that everyone who looks on the Son and believes in him should have eternal life, and I will raise him up on the last day.”
Joh 6:41 So the Jews grumbled about him, because he said, “I am the bread that came down from heaven.”
Joh 6:42 They said, “Is not this Jesus, the son of Joseph, whose father and mother we know? How does he now say, ‘I have come down from heaven’?”
Joh 6:43 Jesus answered them, “Do not grumble among yourselves.
Joh 6:44 No one can come to me unless the Father who sent me draws him. And I will raise him up on the last day.
Joh 6:45 It is written in the Prophets, ‘And they will all be taught by God.’ Everyone who has heard and learned from the Father comes to me—
Joh 6:46 not that anyone has seen the Father except he who is from God; he has seen the Father.
Joh 6:47 Truly, truly, I say to you, whoever believes has eternal life.
Joh 6:48
I am the bread of life.
Joh 6:49 Your fathers ate the manna in the wilderness, and they died.
Joh 6:50
This is the bread that comes down from heaven, so that one may eat of it and not die.
Joh 6:51
I am the living bread that came down from heaven. If anyone eats of this bread, he will live forever. And the bread that I will give for the life of the world is my flesh.” (ESV)
Jesus clearly believes that he has come down from heaven, as the true, living bread, just as the manna came down from heaven. That is his whole point.
John's water baptism was from heaven according to Luke 20:4-8 but it wasn't rained down from the sky. Being from heaven sometimes means from the authority of God.
The clear meaning is that John's baptism was given by God, that his authority came from God, which is the very thing Jesus was trying to prove about himself in response to the question he was asked.
So to even make your doctrine work, you should have clear examples of Jesus saying or doing anything in a pre-existent state.
This is all just fallaciously begging the question. You would have a much better understanding of what the Bible says if you would stop using poor reasoning and get a grasp on basic hermeneutic principles.
Yes it's required to have Biblical evidence to believe things.
Yet, I've given you
lots, but you either ignore it, dismiss it, or mistranslate it because you don't seem to understand basic hermeneutic principles, such as context and that clear Scripture interprets less clear Scripture. You take everything piecemeal and that will almost always lead to error.
