Many faiths ask where Jesus proclaimed his deity. Some faith will even say that Jesus has to do it in whatever words they decide he must say. Which is just nonsense.
Anyway, Jesus proclaimed his deity in multiple times and in multiple ways. One of the big places is here.
And when he returned to Capernaum after some days, it was reported that he was at home. And many were gathered together, so that there was no more room, not even at the door. And he was preaching the word to them. And they came, bringing to him a paralytic carried by four men. And when they could not get near him because of the crowd, they removed the roof above him, and when they had made an opening, they let down the bed on which the paralytic lay. And when Jesus saw their faith, he said to the paralytic, “Son, your sins are forgiven.” Now some of the scribes were sitting there, questioning in their hearts, 7 “Why does this man speak like that? He is blaspheming! Who can forgive sins but God alone?”
And immediately Jesus, perceiving in his spirit that they thus questioned within themselves, said to them, “Why do you question these things in your hearts? Which is easier, to say to the paralytic, ‘Your sins are forgiven,’ or to say, ‘Rise, take up your bed and walk’? But that you may know that the Son of Man has authority on earth to forgive sins”—he said to the paralytic— “I say to you, rise, pick up your bed, and go home.” And he rose and immediately picked up his bed and went out before them all, so that they were all amazed and glorified God, saying, “We never saw anything like this!”
Only God can forgive sins.
Jesus forgave sins.
He also healed the man. He healed him so that they would know that he also had authority to forgive sins.
When they asked, “Who can forgive sins but God alone?” They were completely correct. Which is why Jesus forgave his sins.
The whole point of Jesus’ coming was for the forgiveness of sins. Outside of forgiveness, we are eternally separated from God. Jesus bridged that gap.
That’s why Jesus is our only hope.
