I think I already mostly answered this in my post further up about our fulfilling our purpose.

Just to fill in some gaps, though:


23 On that day some Sadducees (who say there is no resurrection) came to Jesus and questioned Him, 24 asking, “Teacher, Moses said, ‘IF A MAN DIES HAVING NO CHILDREN, HIS BROTHER AS NEXT OF KIN SHALL MARRY HIS WIFE, AND RAISE UP CHILDREN FOR HIS BROTHER.’ 25 “Now there were seven brothers with us; and the first married and died, and having no children left his wife to his brother; 26 so also the second, and the third, down to the seventh. 27 “Last of all, the woman died. 28 “In the resurrection, therefore, whose wife of the seven will she be? For they all had married her.”

29 But Jesus answered and said to them, “You are mistaken, not understanding the Scriptures nor the power of God. 30 “For in the resurrection they neither marry nor are given in marriage, but are like angels in heaven. 31 “But regarding the resurrection of the dead, have you not read what was spoken to you by God: 32 ‘I AM THE GOD OF ABRAHAM, AND THE GOD OF ISAAC, AND THE GOD OF JACOB’? He is not the God of the dead but of the living.” 33 When the crowds heard this, they were astonished at His teaching.

What will your brain-damaged brother be like when he is "like an angel in heaven?"

"For now we see things as in a dull (metal) mirror but then we shall see face to face." Does it matter that your brother's mirror is particularly dull at this moment?

Anyways, if you want to live a good life and then be completely wiped out of existence, pray for it. Perhaps the Lord will make an exception for you. I'd be curious about the next turn in the road, myself.

The day my brother died he had an experience first where he almost died - went to use the toilet, came out and told our mom, "they came to get me but I told them 'not yet.'" Then he talked to our dad on the phone for the last time and then sat back in his chair and died after that. Whoever "they" were, they were friendly. Nice that they let him have one more chat, don't you think? It isn't a bureaucracy there.
