"What happens to a person's soul who suffers brain damage? A person's personality can dramatically change after brain injuries, but does it affect their soul? Will they act brain damaged in heaven?"
When I was 7 years old I had a stroke, I should be dead, mentally retarded, or at very least physically disabled. But I was incredibly fortunate, I survived with little damgage, my sight was only damaged a little, yet I can still drive and play football better than you. I did well at school, and am starting at a prestige university next monday. I am 19 years old.
I never talk about this, but since this is an anonymous site, why not.
To anwser question, I don't know for certain, but I believe my personality changed the day I arrived at hospital in intensive care. As it is a lot of trauma to go through for any 7 year old. Yet here I am, I believe Jesus died for me, my parents being athiest, and I was brought up as an athiest. Here I am believing in God.
So my anwser to your question is that God works in all kinds of people.
If you could see me now you would never have thought I had been through, what I have been through.
and no they will not act 'brain damaged', as you put it, in heaven.
A more difficult question to ask would be, what happens to those who have are mentally retarded from birth, how are they judged on judgement day. Unable to even speak, or comprehend english, through out their life, always with a carer. They cannot understand the concept of 'God', and their IQ falls at 40 or below. Are they saved by Christ? When they cannot even understand the concept of salvation?
Thats what I will ask God when I get there. If i get there.
