Jesus said that the world did not know God.
By this he meant that the traditional image of God as a harsh judge and punisher of humankind was false.
He told us that God is our Father.
He said that God judges no one.
He said that God is merciful and forgiving.
He said that God is Love.
For that he was crucified.
The custodians of the traditional image of God felt threatened by him.
They stood to lose their hold on the people.
So they conspired with the secular power - the Romans - to kill him.
The Romans for their part made an example of him - crucifying the King of the Jews.
And later Christian authorities reinstated the harsh image of God which had sustained the Pharisees before them.
