A lot of Christians profess to be saved, a lot of Christians profess there is no hell. Listen, if you're a born again Christian, then there is one thing you understand about your salvation, and that's when you got saved, hell is what you got saved from. Scripture is simple and makes plain and clear our understanding about hell.
If a preacher doesn't believe in hell then what are you listening to him for? Because if there is no hell you have nothing to worry about and he's wasting your time, stop listening to to him and get on with your life. However, if there is a hell then he's a liar, you need to stop listening to him, and warn others by telling them about the good news, that is today is the day of salvation and Jesus saves!
