The teaching that there is an eternal hell in which hordes of mankind will suffer eternal punishment can be a difficult doctrine to accept. The Bible teaches that there is a fiery hell, a place that Jesus warned people about.
Eternal fire is real.
Jesus said it was. In fact, Jesus spoke more of hell than He did of heaven. It is what Jesus came here to save us from. There will be a Day of Judgment when all people will face God. Those who are not covered by the sacrifice of Jesus on the Cross will be cast out into hell where they will undergo eternal punishment.
