Jesus was not the son of God in any physical way. He was created much the same as Adam was created by the will of God in the womb of the Virgin Mary. Jesus was special and placed above all of mankind but not above or equal to God.

Holy Quran

0 Maryam (Mary)! Verily, Allah (The God) gives you the glad tidings of a Word ["Be!" - and he was! I.e. Isa (Jesus) the son of Maryam (Mary)] from him, his name will be the Messiah, Isa (Jesus), the son of Maryam (Mary), held in honor in this world and in the Hereafter, and will be one of those who are near to Allah. -- Surat-u Ali Imran (3): 45

Holy Bible

For You (God) granted him (Jesus) authority over all people that he might give eternal life to all those You have given him. Now this is eternal life: that they may know You, the only true God, and Jesus Christ whom You have sent.
John 17:2-3

Paul one of the early followers of the teachings of Jesus wanted to spread the message of Jesus to the pagan empire of Rome. He taught that the ways of Jesus was to worship one God and to love one another more than oneself. His teachings did not persecute the existing Roman religions but only brought the true message. This made Christianity portable by not attacking others. The Romans soon accepted Christianity as their religion. It was accepted because Christianity had been taught that God had a son named Jesus. They were taught that Jesus was human and susceptible to death. Being a son God meant that God was also the same and could be killed are conquered by man if given the right opportunity. The historical Rome had many gods in the past and all were great but not invincible. Most of the gods had children with great powers or strength. Roman and Greek leaders would aspire to reach the level of God themselves. Many would claim they had ancestry to the Gods.

In the year 325 Christianity had covered all of Rome. But there was a small group that followed a bishop named Arius whom could not accept that Jesus was the Son of God literally as most Romans believed. They believed he was created in a similar fashion to that of Adam. The Roman leader Constantinople held a meeting of many church leaders to set firm what the church thought was right. Arius was was condemned as being wrong and eventually exiled from Rome. It was decided by the majority that Jesus, The Holy Spirit, and God were all the same creating a trinity. This allowed for the Roman belief that man was equal to God.

The Romans, Greeks, and many modern day belief systems revere man as being the creator of religion and God, not the other way around. Modern day school systems in the USA and much of the world today teach that man created himself by the way of evolution, making himself the creator.

I feel that many Christians today know the truth in their hearts, but why do they not speak for what they believe. Is it a fear of being persecuted. Why do they still allow that mankind proclaims to be equal with God by using the words Son and Father. God is one and master of all.

I Know it is a lot of reading but I think that Luke chapter 1 explains this best. I can not find any one single verse that explains it without taking it out of its original context.

First it talks about the miraculous conception of John then of Jesus. They were both blessings bestowed by the will of God unto the people by the Holy Spirit. But they were both physicaly as human as you and I. They were not Gods and were not born in the wombs of a goddess but normal women that God had found special favor with.

Luke 1
1Forasmuch as many have taken in hand to set forth in order a declaration of those things which are most surely believed among us, 2Even as they delivered them unto us, which from the beginning were eyewitnesses, and ministers of the word; 3It seemed good to me also, having had perfect understanding of all things from the very first, to write unto thee in order, most excellent Theophilus, 4That thou mightest know the certainty of those things, wherein thou hast been instructed.
5There was in the days of Herod, the king of Judaea, a certain priest named Zacharias, of the course of Abia: and his wife was of the daughters of Aaron, and her name was Elisabeth. 6And they were both righteous before God, walking in all the commandments and ordinances of the Lord blameless. 7And they had no child, because that Elisabeth was barren, and they both were now well stricken in years. 8And it came to pass, that while he executed the priest’s office before God in the order of his course, 9According to the custom of the priest’s office, his lot was to burn incense when he went into the temple of the Lord. 10And the whole multitude of the people were praying without at the time of incense. 11And there appeared unto him an angel of the Lord standing on the right side of the altar of incense. 12And when Zacharias saw him, he was troubled, and fear fell upon him. 13But the angel said unto him, Fear not, Zacharias: for thy prayer is heard; and thy wife Elisabeth shall bear thee a son, and thou shalt call his name John. 14And thou shalt have joy and gladness; and many shall rejoice at his birth. 15For he shall be great in the sight of the Lord, and shall drink neither wine nor strong drink; and he shall be filled with the Holy Ghost, even from his mother’s womb. 16And many of the children of Israel shall he turn to the Lord their God. 17And he shall go before him in the spirit and power of Elias, to turn the hearts of the fathers to the children, and the disobedient to the wisdom of the just; to make ready a people prepared for the Lord. 18And Zacharias said unto the angel, Whereby shall I know this? for I am an old man, and my wife well stricken in years. 19And the angel answering said unto him, I am Gabriel, that stand in the presence of God; and am sent to speak unto thee, and to show thee these glad tidings. 20And, behold, thou shalt be dumb, and not able to speak, until the day that these things shall be performed, because thou believest not my words, which shall be fulfilled in their season. 21And the people waited for Zacharias, and marvelled that he tarried so long in the temple. 22And when he came out, he could not speak unto them: and they perceived that he had seen a vision in the temple: for he beckoned unto them, and remained speechless. 23And it came to pass, that, as soon as the days of his ministration were accomplished, he departed to his own house. 24And after those days his wife Elisabeth conceived, and hid herself five months, saying, 25Thus hath the Lord dealt with me in the days wherein he looked on me, to take away my reproach among men.

Conception Of jesus

26And in the sixth month the angel Gabriel was sent from God unto a city of Galilee, named Nazareth, 27To a virgin espoused to a man whose name was Joseph, of the house of David; and the virgin’s name was Mary. 28And the angel came in unto her, and said, Hail, thou that art highly favoured, the Lord is with thee: blessed art thou among women. 29And when she saw him, she was troubled at his saying, and cast in her mind what manner of salutation this should be. 30And the angel said unto her, Fear not, Mary: for thou hast found favour with God. 31And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name JESUS. 32He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David: 33And he shall reign over the house of Jacob for ever; and of his kingdom there shall be no end. 34Then said Mary unto the angel, How shall this be, seeing I know not a man? 35And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God. 36And, behold, thy cousin Elisabeth, she hath also conceived a son in her old age: and this is the sixth month with her, who was called barren. 37For with God nothing shall be impossible. 38And Mary said, Behold the handmaid of the Lord; be it unto me according to thy word. And the angel departed from her.
39And Mary arose in those days, and went into the hill country with haste, into a city of Juda; 40And entered into the house of Zacharias, and saluted Elisabeth. 41And it came to pass, that, when Elisabeth heard the salutation of Mary, the babe leaped in her womb; and Elisabeth was filled with the Holy Ghost: 42And she spake out with a loud voice, and said, Blessed art thou among women, and blessed is the fruit of thy womb. 43And whence is this to me, that the mother of my Lord should come to me? 44For, lo, as soon as the voice of thy salutation sounded in mine ears, the babe leaped in my womb for joy. 45And blessed is she that believed: for there shall be a performance of those things which were told her from the Lord. 46And Mary said, My soul doth magnify the Lord, 47And my spirit hath rejoiced in God my Saviour. 48For he hath regarded the low estate of his handmaiden: for, behold, from henceforth all generations shall call me blessed. 49For he that is mighty hath done to me great things; and holy is his name. 50And his mercy is on them that fear him from generation to generation. 51He hath showed strength with his arm; he hath scattered the proud in the imagination of their hearts. 52He hath put down the mighty from their seats, and exalted them of low degree. 53He hath filled the hungry with good things; and the rich he hath sent empty away. 54He hath holpen his servant Israel, in remembrance of his mercy; 55As he spake to our fathers, to Abraham, and to his seed for ever. 56And Mary abode with her about three months, and returned to her own house.
57Now Elisabeth’s full time came that she should be delivered; and she brought forth a son. 58And her neighbours and her cousins heard how the Lord had showed great mercy upon her; and they rejoiced with her. 59And it came to pass, that on the eighth day they came to circumcise the child; and they called him Zacharias, after the name of his father. 60And his mother answered and said, Not so; but he shall be called John. 61And they said unto her, There is none of thy kindred that is called by this name. 62And they made signs to his father, how he would have him called. 63And he asked for a writing table, and wrote, saying, His name is John. And they marvelled all. 64And his mouth was opened immediately, and his tongue loosed, and he spake, and praised God. 65And fear came on all that dwelt round about them: and all these sayings were noised abroad throughout all the hill country of Judaea. 66And all they that heard them laid them up in their hearts, saying, What manner of child shall this be! And the hand of the Lord was with him.
67And his father Zacharias was filled with the Holy Ghost, and prophesied, saying, 68Blessed be the Lord God of Israel; for he hath visited and redeemed his people, 69And hath raised up an horn of salvation for us in the house of his servant David; 70As he spake by the mouth of his holy prophets, which have been since the world began: 71That we should be saved from our enemies, and from the hand of all that hate us; 72To perform the mercy promised to our fathers, and to remember his holy covenant; 73The oath which he sware to our father Abraham, 74That he would grant unto us, that we being delivered out of the hand of our enemies might serve him without fear, 75In holiness and righteousness before him, all the days of our life. 76And thou, child, shalt be called the prophet of the Highest: for thou shalt go before the face of the Lord to prepare his ways; 77To give knowledge of salvation unto his people by the remission of their sins, 78Through the tender mercy of our God; whereby the dayspring from on high hath visited us, 79To give light to them that sit in darkness and in the shadow of death, to guide our feet into the way of peace. 80And the child grew, and waxed strong in spirit, and was in the deserts till the day of his showing unto Israel.
