If you mean God the father, God the son and God the holy spirit then I can see where you are coming from. To me there is a clear distinction between God and Jesus as I have previously shown. As fas as man's spirit not being from God consider the following;
Job 33:4
The Spirit of God hath made me, and the breath of the Almighty hath given me life.
Isaiah 42:4
Thus saith God, he that created the heavens, and stretched them out; he that spread forth the earth, and that which cometh out of it; he that giveth breath unto the people upon it, and spirit to them that walk therein:
Again, we may agree to disagree because we are coming from two different areas of thinking. I haven't seen evidence of Jesus being the creator only being the created.
The (word) is that of truth.
Quran
19:34
That is Jesus, son of Mary, in word of truth, concerning which they are doubting.
He came confirming their way of life and told them it would not change nor was he here to change it. He also came declaring "There is no god but God and all praise is due to God". Jesus came to his people (lost sheep of the house of Israel) because they had seriously gone astray from the (word) of God.
Jesus was not God. He said it and God said it.
Numbers 23:19
For God is not a man that he should sin neither is God the son of man that he shall have to repent.
Quran
5:116
And when God said, 'O Jesus son of Mary, didst thou say unto men, "Take me and my mother as gods, apart from God"?' He said, 'To Thee be glory! It is not mine to say what I have no right to. If I indeed said it, Thou knowest it, knowing what is within my soul, and I know not what is within Thy soul; Thou knowest the things unseen.
If you believe that the bible and the quran are in harmony then you must agree that God has no son and Jesus is not God. This is the position of the quran. Jesus' "divinity" was granted to him by God, as shown in the quran.
5:110
When God said, 'Jesus Son of Mary, remember My blessing upon thee and upon thy mother, when I confirmed thee with the Holy Spirit, to speak to men in the cradle, and of age; and when I taught thee the Book, the Wisdom, the Torah, the Gospel; and when thou createst out of clay, by My leave, as the likeness of a bird, and thou breathest into it, and it is a bird, by My leave; and thou healest the blind and the leper by My leave, and thou bringest the dead forth by My leave; and when restrained from thee the Children of Israel when thou camest unto them with the clear signs, and the unbelievers among them said, "This is nothing but sorcery manifest."
