Hell is real.
"And whosoever was not found
written in the book of life was cast
into the lake of fire."
Revelation 20;15

It is a literal hell and is the future
home of those who refuse God in
this life.....

"But the fearful, and unbelieving,
and the abominable, and murderers,
and whoremongers, and sorcerers,
and idolaters, and all liars, shall have
their part in the lake which burneth
with fire and brimstone: which is the
second death." Revelation 21:8
