Yes, I know that, but as some here have defined this sin, it cannot be forgiven only because it is never committed until you die. Of course after you die, no sin will be forgiven.
But the way I see it is if you can commit this sin at 30 years old, then no matter what you do the rest of your 80 year life it is too bad, you committed a sin at 30 that damns you and there is no room for repentance later.
How can one commit the unpardonable sin after they die?
