As I understand LDS teaching, a couple may have an eternal family with the children they produce here on earth. However, that couple may also attain godhood and then produce spiritual children for their own worlds as well. Thus, a couple may have both earthly children as well as celestial or spiritual children. Their spiritual children then take on flesh on another world and seek to attain godhood themselves. (This is the doctrine of eternal progression, as I understand it.)
So, my question concerns the relationship of the couple that attains godhood to their spiritual or celestial children and how that is similar or different from the relationship they have with the children they had here on earth.
Do the celestial or spiritual children become part of their eternal family as well? Do spiritual children share equal status with earthly children?
