Heb 13:8 said:
No, it's not about how good you can be. It's about how good Jesus already is. It's about believing on the finished work of the cross.
If you believe the lake of fire is make believe, guess again.
if you believe hell is in some nebulous future, and not in Erets, now, then you are demonstrably following after mythology, and do not understand what Gehenna even is, with all due respect. Why does it never occur to people to question why Greek mythological gods are being invoked, through Anglish translations of Norse mythology, in order to provide us with our current concept of a future "hell?"
This is as demonstrably ridiculous as the assertion that Jesus is going to fly down and save some of us at some undetermined future date, as well. It is a heresy, brought by "women"--the spiritual concept of "women," ladies, actual women is irrelevant here--and well documented and condemned by Ezekiel, and anyone holding it is a closet satanist, and does not know God. It is the musings of the confused, who have a business to run, and cater to peoples' demands to know things for a fact, and ersatz searches for "proof" of some imaginary security that does not exist, and is not from God.
And one is doubly deluded if they think they can ignore works, and refute the Bible where It plainly states, in many, many places, that it is one's works that will be judged.
Which is not to say that hell is make-believe at all--quite the contrary. I mean to say that any concept of some future "hell" in some imaginary time and some imaginary, physical setting is what is the obvious "make believe."
