Bruce Charlton had a very interesting insight into the Mormon belief that God the Father literally begot our spirits in some way:

It is by being children of God that we enter relationship with Him (and Mother in Heaven) – this makes us siblings in a divine family; then by being born to a human father and mother we are related in overlapping human families (which are intended to persist eternally). I think this corresponds to the two great commandments – …thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment. And the second is like, namely this, Thou shalt love thy neighbour as thyself. There is none other commandment greater than these.
