History is full of people who thought the way of God, way of Jesus, way of love, whatever, was for saps.
No human has ever had a clue what the "way" of God is. The "way" of Jesus is not at all well defined (his fault, if he existed). The "way" of love certainly has no universal definition, but is generally accepted as the best way of life, from what I see of the people around me.
However, those who say there is no separation and never has been a separation between God and man seem to gloss over the fact that a relationship is the choice of not one party, but two, even if one of the "people" in the relationship is God.
Seems to me that the person was saying that God is not a person but a part of all of us? Which, while such thesis is merely insanely wild speculation, is certainly not any more insane or wild than speculating that god is a person.
