Here is your explanation like i promised.
Firstly read and understand these verses. John 1: 1-14,
In the beginning was the Word, and the Word was with God, and the Word was God.
2 The same was in the beginning with God.
3 All things were made by him; and without him was not any thing made that was made.
4 In him was life; and the life was the light of men.
5 And the light shineth in darkness; and the darkness comprehended it not.
6 There was a man sent from God, whose name
was John.
7 The same came for a witness, to bear witness of the Light, that all
men through him might believe.
8 He was not that Light, but
was sent to bear witness of that Light.
9 That was the true Light, which lighteth every man that cometh into the world.
10 He was in the world, and the world was made by him, and the world knew him not.
11 He came unto his own, and his own received him not.
12 But as many as received him, to them gave he power to become the sons of God,
even to them that believe on his name:
13 Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
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.
The word WAS WITH God and WAS God. The reason why you see a contradiction is because you put limits on God, humanly limits on God. You incorrectly
assume that God can only exist in one form at one time as any other created being. This verse tells you that the Word was with God and was God and the Word was MADE FLESH and dwelt among us. The word was made flesh, made as a man and then dealt among us and that Word is Jesus Christ.
Even your Quran calls Jesus Christ a word from God. John the baptist was sent to bare witness of the Light, the light that was In the world and was MADE BY him but the world knew him not. John the baptist was sent to bare witness of Jesus Christ, that light who was in the world an the world was MADE BY HIM, as it says in verse 2 and 3, the word in the beginning was with God and all things WERE MADE BY him and without him was not any thing made. Your Quran also confirms that he who John the baptist bore witness of is Jesus Verse 4 says in Him the word was life, and the life was the light of men, John 8:12 'Then spake Jesus again unto them, saying, ''I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.'' '
The identity of Jesus as God is made perfectly clear, he is the word who is God and who was then made flesh, he was then MADE A MAN and dwelt amoung us. He become a man,
He is both God AND Man. The first you quoted in numbers is from the Old testament, before he was made in man, at the point he was not a man, he was still God in heaven.
Exodus 3:13-14,
13 And Moses said unto God, Behold, when I come unto the children of Israel, and shall say unto them, The God of your fathers hath sent me unto you; and they shall say to me, What is his name? what shall I say unto them?
14 And God said unto Moses, I Am That I Am: and he said, Thus shalt thou say unto the children of Israel, I Am hath sent me unto you.
John 8:58, Jesus said unto them, 'Verily, verily, I say unto you, Before Abraham was, I am'
Understand what Jesus is saying in that verse. Firstly he is saying he pre-existed Abraham, which wouldn't be possible if he was merely a man but is because he is the word which was with God and WAS God from the beginning and which created everything and was MADE A MAN and dwelt among us. Before Abraham was, I AM. He is claiming the name of God, the I AM who spoke to Moses. Jesus Christ was the voice in the burning bush who spoke to Moses. Just like the Word was with God and IS God the two together, that word was made flesh in Jesus Christ and that word
Jesus Christ is STILL God but he is also flesh, he is also a man. The limits you put on God and his existence, assuming he is not capable of existing in two different forms at the same time is why you find a contradiction,
GOD HAS NO LIMITS.
Now when he came down to dwell among us as a human in the flesh he was subject to the limits of the flesh.
He took on a human body and came as a man so in the form of a man he was subject to the laws of the flesh. Hence why Satan tried to tempt him in the wilderness, God cannot be tempted, but seeing as he was in the form of a man,
living in the flesh and subject to the limits God himself place on the flesh Satan attempted it. And that is why he it was his Godly form who had to do the miracles through him, God has no limits, but in the form of A man he subjected himself to the limits of man hence why it was the Godly form that did the works through him.
In matthew 19:17 Jesus rebuked that man because the man spoke out of Ignorance. As it says in John 1:10 'he was in the world but the world knew him not', that man didn't know he was God, he thought he was simply a man and yet he called him Good master. Jesus would not commend him for saying something out of ignorance. He knew Jesus not as God but as just a man, so therefore based on what he knew he should not have called him Good master.
Jesus didn't deny he was God, he never said he wasn't God, he just asked why the man, who didnt know he was God had called him good master when only God is good.
John 14:8
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?.
The man in matthew knew not Jesus as God therefore Jesus rebuked him for calling him God master, but in the verse above Jesus rebukes Philip for the exact opposite. Jesus is saying that considering how long he has been with Philip, he should know who Jesus is by now.
John 20,
'28 And Thomas answered and said unto him, My Lord and my God.
29 Jesus saith unto him, Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed.
' Here Thomas the disciple calls Jesus Lord and God. Because he knows who Jesus is.
Luke 7:48-50
'48 And he said unto her, Thy sins are forgiven.
49 And they that sat at meat with him began to say within themselves, Who is this that forgiveth sins also?
50 And he said to the woman, Thy faith hath saved thee; go in peace.' Here we see Jesus Christ forgive this woman's sins.
John 14
5 Thomas saith unto him, Lord, we know not whither thou goest; and how can we know the way?
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.
Jesus is called the Lord throughout the bible, and in the Old testament before Jesus came to earth God was called the Lord. Exodus chapter 5 for example
1 And afterward Moses and Aaron went in, and told Pharaoh, Thus saith the Lord God of Israel, Let my people go, that they may hold a feast unto me in the wilderness.
2 And Pharaoh said, Who is the Lord, that I should obey his voice to let Israel go? I know not the Lord, neither will I let Israel go.
