Could God change you so that you are something other than human, or are you forced to live eternally as what you are? Could He change your being if you so desired, or would that be a sort of “twisted and unnatural” desire which could never be sincere?
Could He? Technically, yes. He has the power to transform us into whatever He wills.
Would He? It depends on what you mean by human.
We are man, by our nature, and when we are baptized, we are said to become a new ‘creature’, or a new ‘creation’. We are still human, but we are born anew in Christ. And when we die, we are given glorified bodies. We are eternally Man, before and after baptism, before and after death, always.
Now, if you are asking if God would change us into something other than Man or human, such as an animal, or a mythological creature, then no, we have no evidence to suggest He would do that. Man is considered to be God’s greatest creation.
Why would you desire to be something other than human? Yes, humanity has its faults, but as an individual you have the free will to do wonderful things.
Might I ask from what thoughts spawned this question?
