What about “I and the Father are one?” That explicitly means that Jesus is God.
The verse does not imply any equality in deity and it cannot be interprated separately from the whole passage. Jesus preached people to believe in him and performed some miracles. But people did not believe him. Jesus said “the works that I do in my Father’s name, they bear witness of me.” Here Jesus do not talk about deity of himself but about his work which He made in name of Father.
When people intent to stone him then Jesus asked for what? They said " because that thou, being a man, makest thyself God." Jesus answered: " Is it not written in your law, I said, Ye are gods? If he called them gods, unto whom the word of God came, and the scripture cannot be broken;"
The word of God came to Jesus so Jesus talk in that way. Jesus was sent by God and were given all authority by God to preach. In that manner Jesus and God are one means that order and words of Jesus are authorized by God. Otherwise Jesus did not confirm claim of being deity. He rejected that. And notice that Jesus always said that “Father sent me” or “all were given me by Father” etc. Here Jesus never assert to be deity. Those are also explained in Qur’an:
49- And [make him] a messenger to the Children of Israel, [who will say], 'Indeed I have come to you with a sign from your Lord in that I design for you from clay [that which is] like the form of a bird, then I breathe into it and it becomes a bird by permission of Allah. And I cure the blind and the leper, and I give life to the dead – by permission of Allah. And I inform you of what you eat and what you store in your houses. Indeed in that is a sign for you, if you are believers. Ali-Imran(3)
110- [The Day] when Allah will say, "O Jesus, Son of Mary, remember My favor upon you and upon your mother when I supported you with the Pure Spirit and you spoke to the people in the cradle and in maturity; and [remember] when I taught you writing and wisdom and the Torah and the Gospel; and when you designed from clay [what was] like the form of a bird with My permission, then you breathed into it, and it became a bird with My permission; and you healed the blind and the leper with My permission; and when you brought forth the dead with My permission; and when I restrained the Children of Israel from [killing] you when you came to them with clear proofs and those who disbelieved among them said, “This is not but obvious magic.” Al-Maidah(5)
Pure Sipirit is Holy Spirit. Jesus were supported by Holy Spirit.
