Anyone who reads the Bible carefully, will notice that the Bible itself disproves the claim that Jesus is the Son of God, and it clearly shows that he, as claimed by the Koran, was a prophet and messenger of God. The concept of God's Son is close to the Roman polytheism and also the Hindu polytheism where an incarnated God is called Avatar (e.g. Krishna), but not to the religion of Abraham. It was the Roman Paul, the real founder of Christianity and a former enemy of monotheism, who introduced this idea, if we follow history carefully.
Jesus and the devil in the Bible
In the New Testament, in the fourth chapter of Matthew, the sixth and seventh verse show quite clear that Jesus was an obedient mortal and God his Lord and Master, according to his Jesus' own statement:
Thou shalt not tempt the Lord thy God.
In this chapter, we read that the devil carries the Messiah from place to place. How can the devil carry God? Praised be God; He is above such blasphemy.
Then the devil asks Jesus to prostrate before him and worship him, trying him even with worldly possessions and power. How can the Devil even dare such audacity with God? When the devil tempted Jesus, Jesus answered like written in all holy books:
Then saith Jesus unto him, Get thee hence, Satan: for it is written, Thou shalt worship the Lord thy God, and him only shalt thou serve. [Matthew 4: 10 ]
Children of God
Jesus never called himself the Son of God so far as it is known, but the Son of Man (Mark 2:10), although he did not complain if he was so called - as it says in the Bible - but did not understand this title to be reserved for him only. In the biblical terminology of the Old and New Testament, every God-fearing, sincere person is called a child of God, as we read in Matthew:
Blessed are the peacemakers: for they shall be called the children of God.
[Matthew 5: 9]
That ye may be the children of your Father which is in heaven ... [Matthew 5: 45]
And call no man your father upon the earth: for one is your Father, which is in heaven. [Matthew 23: 9]
God, the Father
Be ye therefore perfect, even as your Father which is in heaven is perfect.
[Matthew 5: 48]
...otherwise ye have no reward of your Father which is in heaven. [Matthew 6: 1]
The word Father for God is mentioned several times in the Bible, but never exclusively for Jesus.
Jesus, the worshiper
And when he had sent the multitudes away, he went up into a mountain apart to pray: and when the evening was come, he was there alone. [Matthew 14: 23]
If Jesus is God or one with him, why was he praying then? The fact is, a prayer always comes from a devoted, needy being, requiring the grace of the Almighty, as it is mentioned in the Koran:
O mankind. Ye are the poor in your relation to Allah. And Allah. He is the Absolute, the Owner of Praise. [Fatir 15]
There is none in the heavens and the earth but cometh unto the Beneficent as a slave. [Maryam 93]
Jesus, a prophet of God
And, behold, one came and said unto him, Good Master, what good thing shall I do, that I may have eternal life? And he said unto him, Why callest thou me good? There is none good but one, that is, God: but if thou wilt enter into life, keep the commandments. [Matthew 19: 16-17]
In the above verses can be clearly seen the devotion of Jesus to God's will.
And when the chief priests and Pharisees had heard his parables, they perceived that he spake of them. But when they sought to lay hands on him, they feared the multitude, because they took him for a prophet . [Matthew 21: 45-46]
And the one of them, whose name was Cleopas, answering said unto him, Art thou only a stranger in Jerusalem, and hast not known the things which are come to pass there in these days? And he said unto them, What things? And they said unto him, Concerning Jesus of Nazareth, which was a prophet mighty in deed and word before God and all the people. [Luke 24: 18-19]
Here it is proven that all those who believed in Jesus during his lifetime regarded him not as God or the Son of God, or believed in the doctrine of the Trinity, but regarded him as a prophet.
Jesus, a servant of God
But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only. [Matthew 24: 36]
This is a clear indication that the knowledge of Jesus was imperfect and therefore not one with God, and that God alone is the All-knowing.
And he went a little further, and fell on his face, and prayed, saying, O my Father, if it be possible, let this cup pass from me: nevertheless not as I will, but as thou wilt. [Matthew 26: 39]
Here we see that the person speaking does not have the same will as God and it is clearly expressed that he is an obedient servant of God.
Jesus, a preacher of monotheism
And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent. [John 17: 3]
And one of the scribes came, and having heard them reasoning together, and perceiving that he had answered them well, asked him, Which is the first commandment of all? And Jesus answered him, The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord : And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment. [Mark 12: 28-30]
And the scribe said unto him, Well, Master, thou hast said the truth: for there is one God ; and there is none other but He. [Mark 12: 32]
And when Jesus saw that he answered discreetly, he said unto him, Thou art not far from the kingdom of God. [Mark 12: 34]
In these verses, Jesus confesses himself that God is one God and there is no other than him, and that anyone who believes in His oneness, is close to the kingdom of God. That is why he who joins something in worship besides God, or who believes in a Trinity, is far from the kingdom of God. Those who take Jesus as God, betray him and his teachings.
The First Commandment
And verily We have raised in every nation a messenger, [proclaiming]: Serve Allah and shun false gods. [An-Nahl 36]
The first commandment of Moses : I am the Lord thy God, Thou shalt have no other gods before Me.
Lo. Allah forgiveth not that a partner should be ascribed unto Him. He forgiveth [all] save that to whom He will. Whoso ascribeth partners to Allah, he hath indeed invented a tremendous sin. [An-Nisa 48]
Every prophet of God came with the same message: Worship God and believe in me and the commandments which I convey to you from Him. Who does not, is already judged. Jesus was no exception.
What became of God's commandments?
How comes that today's Christians, except from a few Christian sects, seem to ignore the commandments of the Old Testament so completely? Muslims believe that only God can revise His commandments. No one may contradict the commandments of God. Otherwise man would stand higher than God himself. Only Prophets sent by God have the authority to proclaim God's instructions...
