Furthermore, your main point of using quotations from the bible, I would like to point out that the new testament of the bible was written around 50 years after the death of Jesus, it was written by around 40 different men. The new testament was compiled by saint Paul who says “ For the truth of God hath more abounded through my lie unto his glory; why yet am I also judged as a sinner” (Romans 3:7) In this verse Paul has admitted to exaggerating the truth, if he himself has admitted to lying then how can we be sure that the bible is not a fabrication? Saint Paul also disobeyed the teachings of Jesus, he preached to the gentiles, when Jesus told his disciples not to.
“ For there are three that bear record in heaven, the father, the word and the Holy Ghost, and these three are one” (1 John 5:7) This is the verse which you have quoted from the bible. In this verse it is not clear what the Holy Ghost is I assume that the word is the gospel, if these three things are one that means that there is only one God, who has no partners, and therefore Jesus cannot be his son.
“ And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the sprit, seen of angels, preached unto the gentiles, believed in the world received up into glory.” (1Timothy 3:16) this verse shows that God preached to the gentiles, Jesus did not preach to the gentiles and therefore he was not God. Muslims believe that God is omnipotent, his power is everywhere, and he cannot be manifest in the flesh, as it says in the bible. It is probable that this verse has been somehow concocted; the verse says that god was manifest in the flesh; does this mean that god is not alive? Does this mean that Jesus is not alive anymore? Christians believe that God is alive, so this verse is very contradictory.
In the bible it says, “ And Jesus answered him, the first of all the commandments is here. O Israel; the lord our God is one lord” (Mark 12:29). This verse shows that Jesus said that God is one. “ Now in the morning he returned into the city, he hungered. And when he saw a fig tree in the way he came to it, and found nothing thereon but leaves only, he said let no fruit grow on thee, henceforward forever. And presently the fig tree withered away.” If Jesus was God then he would not have cursed the fig tree, God would not curse a living thing, which had done no harm to anyone.
“ I can of my own self do nothing” why would Jesus say that he could not do anything by himself if he was God?
“For my father is greater than I”
Why would Jesus say that his father was greater than him, if he believed that he was God? No one is greater than God.
If Jesus was God on Earth he would have the power to do anything he wished, he would be indestructible, he would be able to destroy his enemies easily, everyone would live in fear of him, it does not seem that everybody was scared of Jesus, he had many enemies and many disciples.
Another argument in favour of this point is that if Jesus was God then why would he need to be born through his mother, like any human being, if he was God why did he need a human to give birth to him? And also why did he die? If he was God shouldn’t he have been immortal?
From all these arguments we can conclude that, Jesus is mentioned as the Son of God only in a metaphorical sense, he was actually just a prophet of God.
