Over and over again the scriptures tell us Hell is real and eternal and it even tells us who goes there and why.
Jesus taught more on the subject of Hell than any other subject. Ask yourself a question.
Why would He teach on it more than any other subject. The answer is because it is real AND He loves us so much He doesn't want anyone to go there.
Why did Jesus die on the cross? It was because He knows that Hell is a real place and a place of eternal punishment. He died on the cross so that you and I do not have to go there. That is the whole reason He came here taking on a human/mortal body, preched for three years, was persecuted the whole time and suffered then died on a horrible wooden cross so that anyone who accepts His free gift of Salvation.
Then, after desire has conceived, it gives birth to sin; and sin, when it is full-grown, gives birth to death.
For the wages is death
Do not be deceived; God is not mocked, for whatever one sows, that he will also reap.
Then I saw a great white throne and him who was seated on it. From his presence earth and sky fled away, and no place was found for them. And I saw the dead, great and small, standing before the throne, and books were opened. Then another book was opened, which is the book of life. And the dead were judged by what was written in the books, according to what they had done. And the sea gave up the dead who were in it, Death and Hades gave up the dead who were in them, and they were judged, each one of them, according to what they had done. Then Death and Hades were thrown into the lake of fire. This is the second death, the lake of fire. And if anyone's name was not found written in the book of life, he was thrown into the lake of fire.
Every reason you have for believing Heaven exists contains the same proof for the existence of Hell. The Bible says just as much about Hell being a real place as it does about Heaven. You are a fool if you accept the teaching of Heaven that is in the bible but reject the teaching of Hell that are in the exact same book.
