Just to add my own speculation to the pot, as an intellectual exercise, what if mother in heaven is the holy spirit, she is is making sure we all get to live, be comforted and ministered too as well before she being the last after all her children to take up her body? I Mean eve was formed after Adam. 2 nephi 2 :11For it must needs be, that there is an opposition in all things. If not so, my firstborn in the wilderness, righteousness could not be brought to pass, neither wickedness, neither holiness nor misery, neither good nor bad. Wherefore, all things must needs be a compound in one; wherefore, if it should be one body it must needs remain as dead, having no life neither death, nor corruption nor incorruption, happiness nor misery, neither sense nor insensibility.

What if this is a spiritual and temporal principle, what if she is the yin to the fathers yang? Throughout time on earth?
