These words of Jesus were extraordinarily powerful and disconcerting to the Jewish leadership. You see they had no trouble with the fact that God works on the Sabbath but when Jesus says that he too, along with God would work on the Sabbath, they knew he was declaring some sort of equality with God which in their ears was blasphemous. He even added weight to what he was saying he used the words “my Father.” What Jesus was declaring to the Jews was that he and the father are one! He was declaring to the Jews that he was in fact God in the flesh.
