Of course he wasn’t dead. Dead is that from which you don’t come back from. If you come back, you weren’t dead.
Um - that’s a nice neat way of describing what death is and what it isn’t. But what if you have been dead for quite a while, maybe two to four days?
What if your body starts to stink from death?
According to John 11:39
Jesus said, Take ye away the stone. Martha, the sister of him that was dead, saith unto him, Lord, by this time he stinketh: for he hath been dead four days.
Cases like this should lead to far more challenges of the ‘brain dead is dead’ standard for organ donation.
