God-Man refers to Jesus having two natures at the same time. The nature of God and the nature of man.
This is very strange because when we speak of the nature of man we are speaking of his KIND or species. We say "mankind".
To speak of Jesus as God-Man is to speak of a different KIND. Mankind has only one nature and if you add another nature you no longer have what is known as manKIND.
2Pe 1:4 Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust.
That passage refers to a time when the saints will have a new nature (divine nature) to replace the old nature (human nature).
The old nature is lustful and sinful. The new nature will be free from that nature.
To say that Jesus has both a divine or Godlike nature and a mankind nature at the same time is to create something new and undefined and could not be related to mankind because mankind are all of the same kind.
A God-Man and another God-Man would be of the same kind.
Jesus Christ did not have two natures. He had and has only one.
Jesus Christ is a man in whom God dwelt as in a temple.
Humans have only one nature, human nature.
For a believer, that means being composed of spirit and soul and body,
I Thessalonians 5:23
And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ.
Is there a flesh facet to human nature? yes
Is there a soul facet to human nature? yes
Is there a apirit facet to human nature? yes
But all are part of a believer's human nature.
Body and soul are supposed to be subordinate to spirit,
Galatians 5
16 This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.
17 For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.
18 But if ye be led of the Spirit, ye are not under the law.
Romans 8
4 That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.
5 For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit.
6 For to be carnally minded is death; but to be spiritually minded is life and peace.
7 Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.
8 So then they that are in the flesh cannot please God.
9 But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
10 And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness.
11 But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you.
12 Therefore, brethren, we are debtors, not to the flesh, to live after the flesh.
13 For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live.
14 For as many as are led by the Spirit of God, they are the sons of God.
15 For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
16 The Spirit itself beareth witness with our spirit, that we are the children of God:
As far as Jesus the anointed is concerned, he was anointed with pneuma hagion and with power by God, Acts 2:38
This occurred at his baptism by John the B.
Previous to that Jesus was a man of body and soul only, what is referred to as the natural man.
He kept himself pure and perfect by obeying the written logos of God, ie, scripture and by obeying his parents, Joseph, his step father and Mary his biological mother.
When he received spirit from God then God could communicate directly with His son, ie, by revelation.
Until then, Jesus had the written logos to learn and live by, which he did without error.
Luke 2
46 And it came to pass, that after three days they found him in the temple, sitting in the midst of the doctors, both hearing them, and asking them questions.
47 And all that heard him were astonished at his understanding and answers.
48 And when they saw him, they were amazed: and his mother said unto him, Son, why hast thou thus dealt with us? behold, thy father and I have sought thee sorrowing.
49 And he said unto them, How is it that ye sought me? wist ye not that I must be about my Father's business?
50 And they understood not the saying which he spake unto them.
51 And he went down with them, and came to Nazareth, and was subject unto them: but his mother kept all these sayings in her heart.
52 And Jesus increased in wisdom and stature, and in favour with God and man.
II Corinthians 5:19 a
19 To wit, that God was in Christ,
It does not say that God was Christ, but that God was in Christ,
Likewise Colossians 2:9
9 For in him dwelleth all the fulness of the Godhead bodily.
It does not say that Jesus is God but that the Godhead dwelt in Jesus the anointed
To have God dwell in you is quite the anointing I must say
And I speak from experience, as should all Christians
Ephesians 3:19
19 And to know the love of Christ, which passeth knowledge, that ye might be filled with all the fulness of God.
The fulness of God dwells in us.
