[Ali Imran]

The reaction of the Jews around Jesus show that they clearly understood these things to be blasphemous claims for a mere man to make. It's one thing to claim to be God; it's quite another to get other monotheistic Jews to believe it. Along with Jesus's own claim to be God, His disciples believed in His Deity very strongly.

You should not use the Pharisees to argue for your faith. They were Jesus's enemies and they accused him of all sorts of things. You would reject all the other accusations against Jesus the Pharisees made. But you will readily stand with them when they accused Jesus of claiming to be God. Why? The answer is clear.

But again, did Jesus deny their accusation? Did he counter their accusation with an argument? Yes and yes. 

So there, Jesus never once said "I am God". And when the Pharisees accused him of claiming to be God, he rejected it. Who told you to believe Jesus is God?
