The 5D Human no longer experience a human will separate from the whole.
There is only God's Will happening through them.
They are free of the trappings of the ego and see their brothers (and sisters) as themselves.
Fifth density humans are able to experience Heaven on Earth because they are no longer bound by the lower laws.
For a time, they might still vacillate between the lower personality and the Higher Self, but eventually the Higher Self takes over and lives through the human self completely.
