This is also column of the doctrine of salvation. Let’s see a synthesis of the message of the Gospel:
Because Jesus also likewise took part of flesh and blood as a human being, it was that He could on the cross destroy the one who had the power of death, that is, the devil, to become heir, and being made perfect, He became the author of eternal salvation unto all who obey him.
Jesus participated in the same Adamic nature, he was a man, understand himself human, one hundred percent. The apostle Paul calls him, the second Adam, precisely because of his human participation.
And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit. 46Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual. 47The first man is of the earth, earthy: the second man is the Lord from heaven. 1st. Corinthians 15:45-47
Let us observe the very witness of Jesus as to his human nature,
Behold my hands and my feet, that it is I myself: handle me, and see; for a spirit hath not flesh and bones, as ye see me have. Luke 24:39
The proclamation of the Gospel does not overlook the theme, on the contrary, it establishes it as a component theme of the proclamation, and establishes that those born in Him have the same capacity of Jesus to overcome sin,
For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh: Romans 8:3
This establishment of the human nature of Jesus, but without sin, makes us understand that the nature of sin is spiritual, that although it manifests itself in the flesh, it actually has its seat in the spirit of human beings, and not in its material body, as it was preached in the Middle Ages.
The proclamation of the Gospel to the Gentiles was no different than the proclamation addressed to the Jews. The Gentiles were also instructed that Jesus was manifested in the flesh. The epistle of the apostle Paul addressed to the Gentile community of Ephesus demonstrates this,
Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace; Ephesians 2:15
The apostle Paul took care to properly instruct on the subject whom he trained for the ministry of the proclamation of the Gospel. The first epistle addressed to Timothy shows us how Paul trained Timothy,
And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory. 1st. Timothy 3:16
The apostle Peter also declares in his epistles how Jesus was manifested in the flesh,
For Christ also hath once suffered for sins, the just for the unjust, that he might bring us to God, being put to death in the flesh, but quickened by the Spirit: 1st. Peter 3:18
Forasmuch then as Christ hath suffered for us in the flesh, arm yourselves likewise with the same mind: for he that hath suffered in the flesh hath ceased from sin; 1st. Peter 4:1
Finally, the apostle John also bears witness to how Jesus was manifested in the flesh; and he adds that those who deny that Jesus was manifested in the flesh belong to a false, heretical, pagan, apostate doctrine, even if they classify themselves as Christians.
Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God: 3And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world. 1st. John 4:2, 3
There is no doubt, Jesus is man, an authentic human being, but unlike the rest of humanity, past, present and future, without sin,
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 4:15
And ye know that he was manifested to take away our sins; and in him is no sin. 1st. John 3:5
Something else that we need to establish is that everything that Jesus developed on earth, whether it be healings, miracles, gifts, wonders, etc., he developed as human and not as God, as established in the Word,
Who, being in the form of God, thought it not robbery to be equal with God: 7But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men: 8And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross. Philippians 2:6-8
Notice how the apostle emphasizes the humanization of God in Jesus,
- made himself of no reputation,
- was made in the likeness of men:
- And being found in fashion as a man,
This helps us to understand the spiritual capacity in Christ that the born-again have. It is not only sin that has no jurisdiction over the person, but also the power of the Holy Spirit working in us,
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. Romans 8:11
 Hebrews 2:14
 Hebrews 5:9
