Everything within the spiritual world is reflected on this earth. In other words, everything on the earth is a shadow, and the things in heaven are the realities of what is on earth.
God established the earthly family system to show us that there is also a family system in heaven. The reason why God made every family on the earth has a father, a mother and children was to reveal that in heaven, as well, there are a Father, a Mother, and children. God's providence is to let us know that there exists a God the Mother in heaven, as well as a God the Father.
