When Jesus talks about this Oneness, he is not speaking in an Eastern sense about an equivalency of being, such that I am in and of myself divine. What he more has in mind is a complete, mutual indwelling: I am in God, God is in you, you are in God, we are in each other.

…While he does indeed claim that “the Father and I are one” (John 10:30)–a statement so blasphemous to Jewish ears that it nearly gets him stoned–he does not see this as an exclusive privilege but as something shared by all human beings.

There is no separation between humans and God because of this mutual interabiding which expresses the indivisible reality of divine love. We flow into God–and God into us–because it is the nature of love to flow.
