This is the Orthodox belief. God the Father remains beyond us, even in heaven.
That's tough for me to accept. It seems to make much more sense that everybody is asleep in their graves right now and nobody is in heaven. It fits in exactly with what Jesus taught about nobody "ascending" to heaven and nobody ever seeing God the father.
At some point I think we will be outside of this physical universe and will be able to "see" and commune with God the father.
