Humans beings are spirits incarnate in human body which makes the body appear to be alive.
In the book of Genesis it says that God made man in his image. And in the book of Revelation it says that there were wars in heaven between Satan and God. Heaven is not a perfect place. Heaven is a tangible mirror image of a barely tangible spiritual dimension both residing within the Infinite Potential.
If you want to know how spirits relate in heaven, look at how human beings related to each other on earth.
In the movies, the same themes of love and hate play out in numerous genres. Cowboy love and love between astronauts. Love on the sea and love in the desert. War in Africa and war in Europe.
Love on earth and love in heaven are the same in different dimensions. The constant is the infinite immortal spirit whose personality is the same in all dimensions.
Heaven is not a place of perfect peace. If that were so all spirits would be non interacting blocks of stone. When spirits interact there is disharmony and chaos not just peace and bliss.
If you want to know how spirits interact in heaven, look around at how humans interact with each other on earth.
