I know that the family is central to God's plan, and that families give you more joy in life than anything else ever could. But I've often wondered why it is necessary for everyone to be sealed together?
I know the classroom answers. We teach in the LDS church that families can be together forever, sealed together by the power of the priesthood under the blessings of the temple, but why is that necessary? Why do we need to be sealed to our children and to our parents when in the beginning we were already part of an eternal family; sons and daughters of God.
What is the significance to coming to earth, raising one of our spirit brethren in mortality as our own physical offspring, then sealing them to us as such for time and all eternity? When we die, we're going to remember the pre-existence, and the relationships we had for an eternity as spirit siblings. Am I going to view my daughter as the spirit sister I knew her has? Or am I forever going to regard her as my very own offspring? After exaltation we teach that we begin families of our own, and produce spirit offspring just like our father in heaven, at which point our mortal children will be our spirit siblings, our children from our brief time in mortality, the spirit aunts and uncles to our new spirit children, as well as their brothers and sisters somehow?
What is it about taking our pre-existing family of children of God, and organizing them into lineages for time and all eternity that is so significant?
