OK, this is my opinion about it, I can't be sure 100% either but here is what I think:

eternal hell doesn't make sense to me either, I am a Christian and I try my best to follow God's laws.

Everyone on earth is a product of their environment, BUT we all have every day choices to make.

A satanic elite banker has choices, and a Christian mother of 2 has choices. The choices are pretty much the same: Do you make the good, just, and correct decision that God wants you to make for Him instead of yourself, or do you make the easy, lazy, quick fix, etc, decision?

This sort of thing is easy to understand, and if you do not give your heart to God and His love, you will be sentenced to hell on the day of Judgement.

NOW, about hell, THIS IS MY OPINION, I DO NOT KNOW IF IT IS TRUE OR NOT because I am not God, the Bible says the following about hell:

I believe that hell lasts for as long as you sinned, the pain that you inflicted on others, yourself, and the world, because of your sins, is lived out through hell. Jesus died on the cross so that we can trade our record with His perfect one, that is why you must ask Jesus into your heart so that He can erase the bad things, and help you to do good. BUT PLEASE, do not think that asking Jesus into your heart will automatically get you into heaven, you have to CONSTANTLY do it, we wake up a sinner every day, so we have to always keep trying to live more and more how God wants us to. Every person is constantly focusing on sin instead of God, and God understands this fully, which is why He sent Jesus Christ.

John 3:16
"For God so loved the world that He gave His one and only Son, that whoever believes in Him shall not perish but have eternal life."

Read the Bible, listen to God, and He will answer your questions. He has led me to the truth, and He will do the same for you or anyone else who wants it! :D
