What makes it obvious to you when Jesus gives names of those involved?? This is the only time He does so which makes it an account of what actually took place and NOT a parable.
The human soul CANNOT die. Therefore the words "death" or "perish" are to be taken as being eternally separated from God Who alone IS LIFE. "Death" and "Perish" will be cast into the lake of fire which CANNOT be extinguished. Look it up and read without putting you twist on it.
Read the rest of your Bible in the LIGHT.
Names do not change a parable into a non parable. This parable has a name. Look up the definition of parable.
It is simply not true that a soul cannot die. Haven't you read in Ezekiel 18 that the soul who sins Shall die??? Or when Jesus said fear the one who can destroy the soul???
The doctrine that the soul can't die originated with Satan in Eden. Remember when he claimed "surely you will not die"? We are Christians not Satanists.
