Kaleb -John 14:9 does not outright state that God "is" this, that, or the other. Like other Jewish rabbis, Jesus did not tend to describe God in the sense of literal attributes. That came from the apostolic college and the Church Fathers.
It's not necessary for us to 'reinvent the wheel.' Don't forget, Jesus specifically referenced the words of Isaiah at the synagogue. But fine, we'll stick to the old testament.
