For some, it is. But how could it be that if God loves us, he sends us to hell?
Maybe, something is missing from this question.
The bible gives us a single, guaranteed path, to victory. Accept Jesus, and win. Short, sweet and to the point. That's all it really takes, but it isn't based on fear. Those who live in Christ, do not have to fear hell. We're promised we'll be saved from spiritual death, so fear isn't a factor.
When Jesus died on Passover, those were really cosmic implications that this all wasn't just by chance. Knowing that Jesus died for our sins, through the parable of Passover, is a beautiful thing. The book isn't about punishing sin, though that certainly does happen, it is about forgiveness of sins. The whole point of the book, is yes you've sinned, but you're also forgiven.
God, time and again, always gives people ample opportunity to repent and be saved. Noah preached about the flood for 120 years before it happened. Even if you want to think of the story as a fairy tale, why would God have waited 120 years to destroy his creation in a flood? Wouldn't be because he was waiting for them to repent, was it?
I believe so.
And that's a beautiful promise, and one I know God intends to keep. What is there to fear?
