God manifested Himself to Israel as the One Living God.
Isaiah 45 5 ¶I am the Lord, and there is none else, there is no God beside me: I girded thee, though thou hast not known me: 6 That they may know from the rising of the sun, and from the west, that there isnone beside me. I am the Lord, and there is none else.
7 I form the light, and create darkness: I make peace, and create evil: I the Lorddo all these things.
This God did by saving Noah, Abraham, Isreal, David etc.
Isaiah 43
1 But now thus saith the Lord that created thee, O Jacob, and he that formed thee, O Israel, Fear not: for I have redeemed thee, I have called thee by thy name; thou art mine. 2 When thou passest through the waters, I will be with thee; and through the rivers, they shall not overflow thee: when thou walkest through the fire, thou shalt not be burned; neither shall the flame kindle upon thee. 3 For I am the Lord thy God, the Holy One of Israel, thy Saviour: I gave Egypt forthy ransom, Ethiopia and Seba for thee.
And now the Christians met Him in their Lives too. Where God saved them also. In becoming a Father to them. This He did in His Word that Creates everything. He is the Creator God that creates in speaking.
Gen. 1
3 And God said, Let there be light: and there was light. 4 And God saw the light, that it was good: and God divided the light from the darkness.
And God created the whole earth and all live by speaking. And because He believed in who He was that spoke it all manifested.
Now He spoke in Jesus. Jesus is The Word of God that creates His Children. And The Way God did it was to become The Word Himself. He gave Himself a Body. And became the Son, Jesus Christ. Or The Word, Jesus Christ.
John 1
14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth. 15 ¶John bare witness of him, and cried, saying, This was he of whom I spake, He that cometh after me is preferred before me: for he was before me.
The Life of Jesus or the Soul of Jesus was not that of God's "Son". But God that became your Father in The Son, Jesus.
John 14
6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me. 7 If ye had known me, ye should have known my Father also: and from henceforth ye know him, and have seen him. 8 Philip saith unto him, Lord, shew us the Father, and it sufficeth us. 9 Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Shew us the Father? 10 Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works.
Everything "Jesus" did was actually your Father. Because He "doeth the works". The body is not the Person. It is just the Body of the Person. Because the Real Person is the Soul inside of the Body. Just as you are not "your body". You are what you are in your soul.
And God went and died to save you from your dead in human (Adam) existence in intellect. Which you needed. To be rid of your sinful, wretched human life. And in God's resurrection He gave birth to you as His Beloved Son, Jesus Christ. And you are created by The Word of God on Jesus to be the Real Jesus. Where your Dad died for you and gave birth to you as His Son, Jesus Christ.
Rom 6
1 What shall we say then? Shall we continue in sin, that grace may abound?
2 God forbid. How shall we, that are dead to sin, live any longer therein? 3 Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death? 4 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life. 5 For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection: 6 Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin. 7 For he that is dead is freed from sin. 8 Now if we be dead with Christ, we believe that we shall also live with him: 9 Knowing that Christ being raised from the dead dieth no more; death hath no more dominion over him. 10 For in that he died, he died unto sin once: but in that he liveth, he liveth unto God. 11 Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord.
The cross was your Birth as The Son of God. From your Father. Because in the cross your Father died to be your Father and you died to be the Perfect Son of God. Because any Father give birth to who and what He is. Without being the same as your Father you have no Existence as a Child of God. And in the Word the Perfect Father and Child Relationship is Created. And you are Saved from yourself and your lack of Perfection to be now Perfect and without sin.
1 John 3
9 Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.
And now God enjoys you as His Child. Because now God is no longer "flesh" in Jesus but Spirit in the Holy Spirit.
John 4
21 Jesus saith unto her, Woman, believe me, the hour cometh, when ye shall neither in this mountain, nor yet at Jerusalem, worship the Father. 22 Ye worship ye know not what: we know what we worship: for salvation is of the Jews. 23 But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him.
24 God is a Spirit: and they that worship him must worship him in spirit and in truth.
Now your Dad that died for you and gave birth to you as His Beloved Son, Jesus Christ is with you. To comfort you, to protect you, to provide for you and to raise you as His Beloved Son, Jesus Christ. And the Perfect Father and Son that is seen in the Word of Jesus and His Father is now a Reality in the Real Son, Jesus, and His Dad. In you.
