To continue with the previous post, in the highest heaven, wherein one is a child of God and is a full-fledged member of His family, it is possible to trade off love for power and vice versa, while fully preserving one’s intellect.
A physical equivalent is that an object with a mass can be converted into its rest energy, becoming thereby pure energy; and can possibly coalesce back into a material thing.
So, one can “expand” his being fully into love and subsist in everyone and everything while forsaking the ability to manipulate matter; or one can “solidify” and acquire a body, trading off for this feature some ability to indwell in things by love.
This is done by the blessed at will, as per their enjoyment.
Before the Incarnation and before the Resurrection, souls did not acquire new bodies upon death. Did they therefore exist as pure love? Surely not. Christ had not yet come, and neither, therefore, had the Holy Spirit. So, they must have existed as ghosts, unable to exercise any power over anything; unable even to move! Imagine how your life would be if you were suddenly completely paralyzed yet remained conscious. It (1) would be a horror, and (2) would drive you insane. I’m serious; you’d end up 100% psychotic in no time.
Consequently, the souls of the dead could not have been conscious. They were sleeping, in what is often referred to as the Limbo of the Fathers, the difference being that all the separated souls were there, not just the righteous, and none were in hell.
What Jesus did for us was awaken these souls, gave them lightsome new bodies in whatever lower heaven they ended up, and prepared them for new adventures in this world.
Those who died after the Resurrection and those who die now get such bodies instantly upon death. If they are done here and qualify for the highest heaven, then in addition they acquire the ability to expand and contract as described.
