God is the one supreme being who has always existed, who is all powerful, who is all knowing, and who fills and transcends the universe.
That Almighty God at a particular point in history chose to begin to also exist as a human being (Jesus Christ) but did not stop being the Eternal Spirit who is everwhere. He did this because of his great love for us so he could die a terrible death for our sins and so we could spend eternity with him. You've gotta love a God who who let himself be slapped around and tortured to death because he doesn't want you and me to wind up in hell.
There is only one God who has always existed as a spirit and who 2000 years ago began to exist as a human being while continuing to exist as the eternal spirit.
Jews knew there was only one God. Nobody can tell me that Peter and Paul thought there were 3 Gods or 3 individuals who were a God family.
The view of the apostles was quite clear.Jesus is the one God, the one Lord who is existing a human being.
John 20
27Then saith he to Thomas, Reach hither thy finger, and behold my hands; and reach hither thy hand, and thrust it into my side: and be not faithless, but believing.
28And Thomas answered and said unto him, My LORD and my God.
29Jesus saith unto him, Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed.
30And many other signs truly did Jesus in the presence of his disciples, which are not written in this book:
31But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name.
The relationship between the humanity and diety of Jesus is greatly misunderstood by most Christians. Unfortunately most folks don't really understand who the New Testament claims that Jesus is. I will address it. It will be a rather long post, but if the subject interests you please read it thouroughly.
I don't believe in the Trinity concept of God. I believe that God is one God,one LORD, one Spirit. He is not a family of beings who call themselves God. He is a singular person.
It is impossible that there could be three coequal Almighty beings who share the title "God." Almighty means having all power.
The heartcry of both the Old and New Testament is that there is only one God. I contend that Jesus Christ is the one and only God, the God who said to Moses "I AM" existing as a human being.
Son of God = Son of Man = Christ = Messiah
All of those refer to God becoming a human being to save us from our sins. There is only one God and he ain't a group of spirits that calls himself God.
Jesus is not "a" god or "a" LORD. He is the one and only God, the one and only LORD existing as a human being. That is clearly taught in both the Old and the New Testament.
The phrase "son of God" is a messianic title. It does not mean that Jesus is God Junior. Jesus is also called Son of man, another messianic title. Son of God/Son of Man refers to the fact that the Almighty God was born into this world 2000 years ago as a baby boy who was a man and yet the God who created everything that exists. God himself became the Christ that he had promised would pay the price for sin.
The Old Testament predicted that the Mighty God, the Everlasting Father, would be born in Bethlehem. Of course, he existed before then, but that is the point where he took on humanity.
God took on human flesh and became the Christ to save us from our sins. He had to have a human body to do that.
Isaiah 9
6For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace.
7Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even for ever. The zeal of the LORD of hosts will perform this.
Micah 5
2But thou, Bethlehem Ephratah, though thou be little among the thousands of Judah, yet out of thee shall he come forth unto me that is to be ruler in Israel; whose goings forth have been from of old, from everlasting.
We find this was fulfilled and recorded in the gospels.
Luke 2
10And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people.
11For unto you is born this day in the city of David a Saviour, which is Christ the Lord.
12And this shall be a sign unto you; Ye shall find the babe wrapped in swaddling clothes, lying in a manger.
13And suddenly there was with the angel a multitude of the heavenly host praising God, and saying,
14Glory to God in the highest, and on earth peace, good will toward men.
God (existing as a man) went on to die on a cross
Corinthians 2
7But we speak the wisdom of God in a mystery, even the hidden wisdom, which God ordained before the world unto our glory:
8Which none of the princes of this world knew: for had they known it, they would not have crucified the Lord of glory.
It was the blood of God (existing as a man) that was shed.
Acts 20
28Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood.
The Almighty God himself became the Lamb of God to die a sacrificial death for us.
Revelation 1
7Behold, he cometh with clouds; and every eye shall see him, and they also which pierced him: and all kindreds of the earth shall wail because of him. Even so, Amen.
8 I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty.
Revelation 4
8And the four beasts had each of them six wings about him; and they were full of eyes within: and they rest not day and night, saying, Holy, holy, holy, LORD God Almighty, which was, and is, and is to come.
9And when those beasts give glory and honour and thanks to him that sat on the throne, who liveth for ever and ever,
10The four and twenty elders fall down before him that sat on the throne, and worship him that liveth for ever and ever, and cast their crowns before the throne, saying,
11Thou art worthy, O Lord, to receive glory and honour and power: for thou hast created all things, and for thy pleasure they are and were created.
Jesus said in esense, "if you are looking at me you are looking at the Father" because as I have shown, the Father took on flesh and became known as Jesus Christ.
John 14
7If ye had known me, ye should have known my Father also: and from henceforth ye know him, and have seen him.
8Philip saith unto him, Lord, show us the Father, and it sufficeth us.
9Jesus 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, Show us the Father?
Jesus Christ, our Everlasting Father in flesh, is the only God, the only Savior.
Isaiah 43
10Ye are my witnesses, saith the LORD, and my servant whom I have chosen: that ye may know and believe me, and understand that I am he: before me there was no God formed, neither shall there be after me.
11I, even I, am the LORD; and beside me there is no saviour.
Look back up to Luke 2:11
For unto you is born this day in the city of David a Saviour, which is Christ the Lord.
(Lord with a capital L is always God, Jehovah)
Oh, wonder of wonders that my God would take on a human existance to die for me!
I John3: 16
16Hereby perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brethren.
God did not, by the way, stop being everywhere at the same time because of his incarnation as a man. He did not cease to exist in the way that he has always existed. The incarnation is God taking on another existing in addition to the way he has always existed. When Jesus was talking to Nicodemus he said was in heaven at the same time.
John 3
12If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you of heavenly things?
13And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.
The incarnation of God did have limited knowledge though (but not limited knowledge as the Spirit who transcends space and time. God lived a completely human life in Jesus Christ.
God has always existed as a spirit. In the Incarnation God began to also exist as a human being at the same time as his existance as a spirit.
After the incarnation God exists as the eternal spirit and also as a man who is God existing as a human being. That incarnation is not a separate person but another way that God exists.
Deut 6
44Hear, O Israel: The LORD our God is one LORD:
I want to emphasize that God did not "put on a robe of humanity." He began to exist as an actual real human being without ceasing to exist as the Spirit who is everywheres.
Neither did a separate god come into existance. God is existing at the same time as a spirit and as a man. There are not 2 people here. There is one God existing as an everpresent and all powerful spirit and as a real man at the same time.
Only as a completely real human being could God die for our sins. This is the "mystery of godliness."
1 Tim 3
16And 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.
1 Cor 8
6But to us there is but one God, the Father, of whom are all things, and we in him; and one Lord Jesus Christ, by whom are all things, and we by him.
