Among the prophecies of His coming is the name meaning God With Us. When a teenager asked how the God who created the Universe could be a man, just a man, the following was given for sharing with others on How God The Almighty could be born a human being ... this is the extremely short version.

In John's Gospel, chapter 14, Jesus tells His disciples that if they have seen Him they have seen The Father, for He is in the Father and the Father in Him. All they could see of The Father was Jesus, God with them.

If you were a being who was created with only length and width spatial variability, you could not perceive a sphere of length, width, and height, except where that sphere was in your length x width plane. If I want to show a sphere to these flatlanders (from the short novel, Flatland) I would have to pass the sphere through their plane, making a series of expanding circles then shrinking circles.remely short version:

Here is a sort of Physics lesson found in John 14, as Jesus responded to Philip's request to be shown The Father so he could believe Jesus was The Messiah:

There are two axioms which can help with understanding, regarding anything of the Universe, the Universe, and anything in the Universe God has created/is creating:

axiom 1 = without time, events do not occur

axiom 2 = without space a thing does not exist

All things in the Universe God created have some variability of space and time, even a photon. A photon passes or 'events' inside the Universe never going out of the present of its creation, thus it arrives at your eye, for instance, and imparts data of the source at the moment the photon is created, even if it takes a billion years (perceived from our position in the temporal field) to reach your eye. The photon remains in the present of its creation. Photons are a mix of a pinch of space, a moment in time, and energy. Photons carry 'present moment data'.

God made Man to have a physical body, a behavior mechanism or soul, and a third aspect, the spirit, into which God put His Spirit life but which was forfeited in Adam; the human spirit remained but the life on a spirit level was removed, and that is what God puts back into the spirit of a believer in Jesus, a saved person.

The soul is real, it exists in time and space, but in a different coordinate system from the physical body, though it interfaces with same. In the same fashion, spirit is real, having some variability of time and space, though existing in a different coordinate system from the soul yet interfacing with same. When one is 'born from above' (John 3), God puts the earnest of a greater existence into the human spirit. (That is important to comprehend if we are to see what will happen at the Rapture.)

One more clue: the being who wrote upon the wall in Palace Party central (Daniel 5) exists in a spacetime coordinate system un sensible to the partiers, so He reached 'down' into the Palace spacetime coordinate system and wrote on the wall, while the portion not the hand writing remained in a different spacetime coordinate system.

Well, maybe one more: when Stephen was close to death, he looked and saw Jesus standing at the right hand of the throne of The Father; God allowed Stephen to have the ability to see more than the coordinate system in which he was about to die, physically. What Stephen saw was real, had real space and time variability, but was un sensible to those who would be throwing rocks.

In John's Gospel account of Jesus and the coming of the Christ --to be 'God With us' and then God in us following the Resurrection and Church Day of Pentecost,-- in that Gospel we are given the scene of one Nicodemus, member of the Jewish Sanhedrin in that day, coming to Jesus at night to ask Him for something to show He was Messiah. They get into an exchange during which Jesus tells Nicodemus that a man must be born again, born of the Spirit, in order to enter into Heaven.

Throughout the letters of Paul --and especially in the letter to the Romans-- Paul addresses this notion of being born again, born of the Spirit, for Salvation in Christ. And he, Paul, explains it using the verb tenses and cases in the Greek which indicate an immediate deliverance followed by an ongoing transformational process called ‘sanctification’.
 The Blood of Christ cleansed the Mercy Seat in Heaven and thereby those who died before the Cross were made righteous because of their belief (‘faithe‘) in God’s Promises.
 The Blood of Christ cleanses your heart allowing God’s Spirit to come into your inner self, your spirit, and dwell there to transform your soul as you ‘faithe’ in the promises of God to transform you, thereby ‘establishing’ the Law of God (fulfilling the Law) in your heart, as Paul put it.
When one reads these passages in the Greek, there are certain specific aspects of the Greek words which give insight into the specifics of the written passages. Here's a simplified example from Romans chapter ten:
Romans 10:8-10 But what saith it? The word is nigh thee, [even] in thy mouth, and in thy heart: that is, the word of faith, which we preach; That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. (KJV)
Romans 10:8-10 10:8 But what doth it say? `Nigh thee is the saying -- in thy mouth, and in thy heart:` that is, the saying of the faith, that we preach; that if thou mayest confess with thy mouth the Lord Jesus, and mayest believe in thy heart that God did raise him out of the dead, thou shalt be saved, for with the heart doth believe to righteousness, and with the mouth is confession made to salvation; (Young’s Literal Translation)
The underlined words --faith, believe, and believeth-- all derive from the Greek word ‘pisteuo’. In the Greek the verbs give rise to the nouns, so ‘pisteuo’ --to faithe-- gives rise to ‘pistis’, the noun --faith. Important to the understanding of the use of ‘pistis’ is that it is at its heart an action word which, in the way written in the passage, is an ongoing action, an immediate application with continuous force, an unending application --not continuous if referred back to, but a thing instituted by God not man, then remaining in effect WHILE the ‘faither’ lives the remainder of life ‘faithing’.
 Faith is action based upon belief sustained by the confidence that what God promises He will do. That is why we read repeatedly that Abraham ‘believed’ God and it was counted for him righteousness. … The words in blue --confess and confession (’homologeo‘)-- are derived from ‘homos’ which is Greek for ‘at the same place or time’; adding ‘logeo‘ we have ‘at the same time or place spoken‘. … The word in red --salvation (soteria=deliverance)-- is derived from the Greek word ‘soter’, meaning ‘a deliverer’.
It has been offered at FreeRepublic that ’Salvation is a thing that is worked out on one’s knees in prayer and in repentance.’ More accurate it is to say, salvation --deliverance-- is something you receive immediately when you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead. Then you seek to live the rest of your life, daily, as you function in every aspect of living, ‘faithing’ in the promises of God that He will transform your soul by the renewing of your mind.
 You receive deliverance in your spirit and remain delivered in your soul (your behavior mechanism) --are transformed-- through a daily walk (which should include time on your knees and/or in quiet solitude with His Spirit sifting and cleansing your soul) in which you ‘faithe’ in His Spirit within which you received the minute you were delivered.
 You received a deliverer (soter) in your dead human spirit when you confessed Jesus Christ. You are ‘sotered’ daily, to coin a word mixing Greek and English, in your behavior mechanism, your soul.
