Yes, it sure is. Jesus talked about it. He said it was a place where the suffering never ends (Matthew 25:41; Mark 9:48). It’s a curse worse than “being drowned in the sea.” (Mark 9:42) The pain of Hell will produce “weeping and gnashing of teeth.” (Matthew 8:12). Hell is the place reserved for those who reject Jesus in this life.
Hell is a real place, is scary, and is (unfortunately) coming for many people. This grieves us, and motivates us to live self-sacrificially so that others might see the beauty of Christ that we see.
